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

Provided is a voltage monitoring module which includes: a land; and a metal plate arranged on the land and soldered to the land, in which a through-hole is partially formed at a location of the metal plate corresponding to the land, a non-formation area is formed at a location of the land corresponding to part of the through-hole, and no conductor is formed in the non-formation area.

Voltage monitoring module

Provided is a temperature measuring device which includes: a flexible printed circuit board with wiring; a thermistor element; a heat collecting plate; and a pressing member. The flexible printed circuit board is configured to be attached to a case that is fixed to an object to be measured, the thermistor element is electrically connected to the wiring, the heat collecting plate is disposed on a side opposite to the thermistor element via the flexible printed circuit board so as to be pressed against a temperature measuring point in the object to be measured, and the pressing member is made of a foam material and is configured to be compressed when the case is fixed to the object to be measured and to press the heat collecting plate against the object to be measured.

Temperature measuring device

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.
