Provided are a support member and a battery module in consideration of variations in dimensions of the battery. At the same time, stress concentration on the support member is alleviated. A sliding portionof one of adjacent support casesof the plurality of support casesconnected to each other is slidably housed in the main body portionof the other support case. Apart of the sliding portionof the one support caseis pulled out from the main body portionof the other support case. Thus, a distance between the one support caseand the other support caseis increased. At least a part of the sliding portionof the one support caseis housed in the main body portionof the other support case. Thus, the distance between the one support caseand the other support caseis decreased.

Support member and battery module

Provided is a wiring material which is advantageous for space saving while ensuring seismic resistance of a flexible circuit board. A wiring materialincluding a flexible circuit boardin which a plurality of batteriesA toL arranged in one direction is connected to one another via a bus barand an arrangement direction of the batteriesA toL is a longitudinal direction of the flexible circuit board, includes: a narrow connecting portionconnected to the bus bar; and a main bodythat is connected to the connecting portionand includes a portion wider than the connecting portion. The connecting portionis configured to have a longitudinal extending portionthat projects from the main bodyin the longitudinal direction and extends in the longitudinal direction.

Wiring material and battery module

A flexible printed circuit board which includes: a base film; and multiple wires formed on the base film, in which in a region attached to a battery including multiple arrayed cells, a conductor portion to be the multiple wires is provided only on one surface of the base film, at at least part of a region apart from the region attached to the battery, a conductor portion to be the multiple wires is provided on each surface of the base film, and the flexible printed circuit board further includes multiple conductive portions configured to electrically connect the wires on one surface side of the base film and the wires on the other surface side of the base film.

Flexible printed circuit board and battery module

A flexible printed circuit board includes: a trunk portion; and a pair of branch portions as two portions branched from the trunk portion and arranged on a battery including multiple arrayed cells, in which for at least one branch portion of the pair of branch portions, bending is performed using a pair of parallel bending lines extending apart from the other branch portion as extending apart from the trunk portion, and the at least one branch portion is bent such that a direction of bending at one bending line of the pair of parallel bending lines and a direction of bending at the other bending line are directions opposite to each other.

A printed-circuit board includes: a film-shaped thermoplastic base member having plasticity; a pattern fuse formed from a metal foil layer provided on a principal surface of the base member; a cover member covering at least part of the pattern fuse from an opposite side of the base member; and a first heat-resistant protection film provided on a region overlapping with at least part of the pattern fuse and covering the pattern fuse from a cover member side.
