## Abstract

A circuit substrate, a plurality of supporting members that are arranged at intervals in a longitudinal direction of the circuit substrate and support both longitudinal ends of the circuit substrate, and a housing onto which the supporting members are fixed are included.

## Claims

### Claim 1

A circuit-substrate supporting device comprising:
a circuit substrate;
a plurality of supporting members that are arranged at intervals in a longitudinal direction of the circuit substrate and support both longitudinal ends of the circuit substrate; and
a housing onto which the supporting members are fixed.

### Claim 2 (depends on 1)

The circuit-substrate supporting device according to claim 1, wherein
the circuit substrate includes a plurality of notches formed in longitudinal ends at intervals in a longitudinal direction; and the supporting members are arranged in positions corresponding to the notches of the circuit substrate and support both the longitudinal ends of the circuit substrate while being in engagement with the notches.

### Claim 3 (depends on 1)

The circuit-substrate supporting device according to claim 1, wherein
the supporting members each include an elastically deformable base portion, and two substrate-supporting portions that are formed in a standing manner in both ends of the base portion and are provided in inner faces with grooves into which the longitudinal ends of the circuit substrate can be fitted.

### Claim 4

A battery unit comprising:
a circuit substrate;
a plurality of supporting members that are arranged at intervals in a longitudinal direction of the circuit substrate and support both longitudinal ends of the circuit substrate;
a housing onto which the supporting members are fixed; and
batteries supported in the housing and arranged adjacent to the circuit substrate.
