Abstract

Claims (20)

1. A frame member-including inductor, comprising:

a sheet-shaped inductor including a plurality of wirings, and a magnetic layer embedding the plurality of wirings, and

a frame member in which the inductor is set;

wherein the inductor is set in a housing chamber partitioned with the frame member and having four continuous inner-side surfaces,

wherein an outer-side surface of the inductor is spaced apart from the inner-side surfaces of the housing chamber,

wherein the inductor has one surface and the other surface spaced apart from each other in a thickness direction of the inductor,

wherein an outer shape of the magnetic layer is a same outer shape as an outer shape of the inductor, and

wherein a thickness of said frame member is a same thickness as a thickness of the inductor.

2. The frame member-including inductor according to claim 1 , wherein

a plurality of inductors are set in the frame member.

3. A frame member-including laminated sheet, comprising:

the frame member-including inductor according to claim 2 , the frame member having one surface and the other surface, and

a processing stability layer formed on the one surface in a thickness direction of both said inductor and said frame member and including a cured product of a thermosetting resin composition.

4. The frame member-including laminated sheet according to claim 3 , further comprising:

a second processing stability layer formed on the other surface in said thickness direction of said inductor and said frame member and including a cured product of a thermosetting resin composition.

5. A frame member-including laminated sheet, comprising:

the frame member-including inductor according to claim 1 , the frame member having one surface and the other surface, and

a processing stability layer formed on the one surface in a thickness direction of both said inductor and said frame member, and including a cured product of a thermosetting resin composition.

6. The frame member-including laminated sheet according to claim 5 , further comprising:

a second processing stability layer formed on the other surface in said thickness direction of said inductor and said frame member and including a cured product of a thermosetting resin composition.
