Abstract

A wiring board includes a base including a hole part, an inner circumferential end part forming the hole part, and a wiring line including a part surrounding the hole part. The inner circumferential end part of the base is arranged at an inner side than the part surrounding the hole part. The inner circumferential end part of the base is deformed in a direction passing through the hole part.

Claims (36)

1 . A wiring board comprising:

a base including a hole part and an inner circumferential end part forming the hole part; and

a wiring line including a part surrounding the hole part,

wherein the base has a first surface, and a second surface at an opposite side of the first surface in a direction passing through the hole part,

wherein:

the base is a film formed of resin material,

the wiring line is formed at the first surface of the base,

a part of the wiring line surrounding the hole part includes a land,

the inner circumferential end part of the base is disposed at an inner side than the part of the wiring line surrounding the hole part,

the inner circumferential end part of the base is deformed in the direction passing through the hole part, and

a conductive member is provided at the first surface side of the inner circumferential end part of the base and is configured to electrically connect a columnar conductive member, which is disposed inside of the hole part, and the wiring line.

2 . The wiring board according to claim 1 , wherein

the inner circumferential end part of the base includes a plurality of projected parts projecting inward of the hole part, and

the plurality of projected parts are lined in a circumferential direction of the hole part.

3 . The rotating device according to claim 2 , wherein the plurality of projected parts are configured to suppress leakage of the conductive member from the hole part.

4 . The wiring board according to claim 1 , wherein

in the direction passing through the hole part, the deformed inner circumferential end part of the base is in contact with an outer circumferential side surface of the columnar conductive member.

5 . The wiring board according to claim 4 , wherein a size of the columnar conductive member is larger than the hole part formed by the inner circumferential end part and smaller than the part surrounding the hole part of the wiring line.

6 . A rotating machine comprising:

a wiring board;

a columnar conductive member; and

a housing,

wherein the wiring board comprises:

a base including a hole part and an inner circumferential end part forming the hole part,

a wiring line including a part surrounding the hole part,

wherein the base has a first surface, and

a second surface at an opposite side of the first surface in a direction passing through the hole part,

wherein:

the base is a film formed of resin material,

the wiring line is formed at the first surface of the base,

a part of the wiring line surrounding the hole part includes a land,

the inner circumferential end part of the base is disposed at an inner side than the part of the wiring line surrounding the hole part,

the inner circumferential end part of the base is deformed in the direction passing through the hole part, and

a conductive member is provided at the first surface side of the inner circumferential end part of the base and is configured to electrically connect the columnar conductive member, which is disposed inside of the hole part, and the wiring line, and

the columnar conductive member is fixed at the housing.

7 . The rotating machine according to claim 6 , wherein the second surface opposes the part of the housing via a member different from the wiring board.
