at least one non-conductive plate member;

at least one conductive member fixed to the plate member;

a secondary battery stacked on the plate member; and

at least one electrode terminal sticking out of a side face of the secondary battery, and held by the conductive member, wherein

the conductive member has notches, so that tops of protruding portions of the notches are in contact with a surface of the electrode terminal.

2. The secondary battery module according to claim 1 , wherein

the conductive member holding the electrode terminal is made up of a plurality of components in combination.

3. The secondary battery module according to claim 1 , wherein

the conductive member holding the electrode terminal includes a component A abutting one face of the electrode terminal, and a component B abutting another face of the electrode terminal.

4. The secondary battery module according to claim 3 , wherein

the component A is fixed to one of the plate members, the one being arranged on the component A on one side, and the component B is fixed to another one of the plate members, the other one being arranged on the component B on another side.

5. The secondary battery module according to claim 1 , wherein
