the average particle diameter of said second pigment is equal to or less than 10 μm, and wherein

the average particle diameter of said first pigment is equal to or greater than 60 μm.

8. The adhesive tape cartridge according to claim 5 , wherein

said first pigment and said second pigment are made of the same material as each other.

9. The adhesive tape cartridge according to claim 5 , wherein

said first pigment has a transmittance of 20% or more.

10. The adhesive tape cartridge according to claim 5 , wherein

a thickness of said first adhesive layer is greater than a thickness of said second adhesive layer.

11. The adhesive tape cartridge according to claim 1 , wherein

said base material layer and said first adhesive layer are in contact with each other, and wherein

said base material layer and said second adhesive layer are in contact with each other.

12. The adhesive tape cartridge according to claim 1 , further comprising: in said housing,

a cover film roll that winds a cover film, one side of the cover film to be bonded to said first adhesive layer of said double-faced adhesive tape in the thickness direction; and

an ink ribbon roll that winds an ink ribbon which transfers ink to an other side of said cover film in the thickness direction, the cover film fed out from said cover film roll.

13. An adhesive tape cartridge comprising:

a housing; and

an adhesive tape roll that is disposed in said housing and winds an adhesive tape,

said adhesive tape comprising:

a first adhesive layer that comprises an adhesive with a first pigment added;

a second adhesive layer that is disposed with one side, in a thickness direction, in contact said first adhesive layer and comprises an adhesive with a second pigment added; and

a separation material layer that is disposed to be in contact with an other side of said second adhesive layer opposite the one side in the thickness direction,

wherein an average particle diameter of said first pigment in said first adhesive layer and an average particle diameter of said second pigment in said second adhesive layer being different from each other.

14. An adhesive tape roll that winds a double-faced adhesive tape,

said double-faced adhesive tape comprising:

a base material layer having a transmittance of 20% or more;

a first adhesive layer that is disposed on one side of said base material layer in a thickness direction and comprises an adhesive with a first pigment added;

a second adhesive layer that is disposed on an other side of said base material layer, opposite to the one side of the base material layer, in the thickness direction and comprises an adhesive with a second pigment added; and

a separation material layer that covers a surface on a side of said second adhesive layer opposite to the base material layer in the thickness direction,

wherein an average particle diameter of said first pigment in said first adhesive layer and an average particle diameter of said second pigment in said second adhesive layer being different from each other.

15. A method of manufacturing an adhesive tape roll, comprising:

applying an adhesive to one side of a base material layer in a thickness direction with a first pigment added, and forming a first adhesive layer;

applying an adhesive comprising a second pigment to an other side of said base material layer, opposite to the one side of the base material layer, in the thickness direction and forming a second adhesive layer, wherein an average particle diameter of said second pigment is different from an average particle diameter of said first pigment;

bonding a separation material layer to a side of said second adhesive layer opposite the base material layer in the thickness direction; and

winding an adhesive tape including said base material layer, said first adhesive layer, said second adhesive layer, and said separation material layer, and forming said adhesive tape roll.
