Abstract

An adhesive film including a first adhesive layer, wherein the first adhesive layer contains a first adhesive component and a plurality of conductive particles, wherein the plurality of conductive particles include first conductive particles that are dendritic conductive particles, and second conductive particles that are conductive particles other than the first conductive particles, each conductive particle containing a non-conductive core and a conductive layer provided on the core, and a part of the plurality of conductive particles is disposed to protrude from one surface of the first adhesive layer.

Claims (22)

1 . An adhesive film comprising an adhesive layer,

wherein the adhesive layer comprises an adhesive component and a plurality of conductive particles, wherein the plurality of conductive particles comprise:

first conductive particles that are dendritic conductive particles; and

second conductive particles that are conductive particles other than the first conductive particles, each second conductive particle comprising a non-conductive core and a conductive layer provided on the core, and

wherein a part of the plurality of conductive particles protrudes from one surface of the adhesive layer.

2 . The adhesive film according to claim 1 , wherein a part of the first conductive particles protrudes from the one surface of the adhesive layer.

3 . The adhesive film according to claim 1 , wherein a part of the second conductive particles protrudes from the one surface of the adhesive layer.

4 . The adhesive film according to claim 1 , wherein a part of the first conductive particles and a part of the second conductive particles protrude from the one surface of the adhesive layer.

5 . The adhesive film according to claim 1 , further comprising an additional adhesive layer that is provided on the one surface of the adhesive layer and comprises an adhesive component different from the adhesive component of the adhesive layer.

6 . The adhesive film according to claim 5 , wherein the adhesive layer has a thickness of 10 μm or more, and the additional adhesive layer has a thickness of 5 μm or less.

7 . A reel body comprising:

a winding core; and

an adhesive tape wound around the winding core,

wherein the adhesive tape comprises a support and the adhesive film according to claim 1 provided on the support, wherein the support faces a surface of the adhesive layer opposite to the one surface thereof.

8 . The reel body according to claim 7 , wherein a part of the first conductive particles protrudes from the one surface of the adhesive layer.

9 . The reel body according to claim 7 , wherein a part of the second conductive particles protrudes from the one surface of the adhesive layer.

10 . The reel body according to claim 7 , wherein a part of the first conductive particles and a part of the second conductive particles protrude from the one surface of the adhesive layer.

11 . The reel body according to claim 7 , further comprising an additional adhesive layer that is provided on the one surface of the adhesive layer and comprises an adhesive component different from the adhesive component of the adhesive layer.

12 . The reel body according to claim 11 , wherein the adhesive layer has a thickness of 10 μm or more, and the additional adhesive layer has a thickness of 5 μm or less.

13 . Connected electronic members comprising:

electronic members, each electronic member comprising a substrate and an electrode formed on one surface of the substrate; and

an adhesive film according to claim 1 electrically connecting the electronic members to each other.
