Title:
FLEXIBLE PRINTED WIRING BOARD AND BATTERY WIRING MODULE
Document Type and Number:
WIPO Patent Application WO/2021/006323
Kind Code:
A1
Abstract:
A flexible printed wiring board according to an aspect of the present invention is provided with: a base film; a conductive pattern layered on one surface of the base film; an excess-length absorption part disposed so as to project from the base film in the planar direction. The excess-length absorption part has: a pattern connection portion connected to the conductive pattern; a linkage part which has a first linear wiring, a first circular-arc wiring, and a second linear wiring linked in this order contiguously from the pattern connection portion; and a connection terminal connected to the linkage part. The pattern connection portion and the connection terminal are opposed to each other in the projecting direction of the excess-length absorption part, the first and second linear wirings are arranged in this order perpendicularly to the projecting direction, and the first circular-arc wiring has both ends aligned in the projecting direction, has a center angle exceeding 180°, and has an inner diameter larger than the average gap between the first and second linear wirings.
