Abstract
Positive and negative terminals formed on a top face of a unit cell and positive and negative terminals formed on a surface of a circuit board opposed to the unit cell are electrically connected to each other by connectors. The connectors each include an elastic body formed from an elastic material, and a conductor which is placed so as to be exposed on upper and lower surfaces of the elastic body and which serves for electrically connecting those exposed portions to each other. By elastic restoring force of the elastic body generated by elastic compression of the elastic body between the terminals, the upper and lower surfaces of the connectors are put into press contact between the opposing positive and negative terminals of the unit cell and the circuit board, by which their electrical connection is maintained.
