To provide a charge/discharge tray for a sheet battery capable of easily ensuring the stable contact of charge/discharge current terminals and voltage measuring terminals, suitable for initial charge/discharge treatment, with high reliability, and used for mass production.

This charge/discharge tray has an electrically insulated placing stand 1; a plurality of battery mounting parts 2 formed on the placing stand 1 surface, positioning and mounting a sheet battery; and conductors 4a, 4b formed in the battery mounting part 2, coming in contact with electrode terminals 3a, 3b of the sheet battery at each one end, and having a plane area larger than the plane area of the electrode terminals 3a, 3b. The battery mounting part 2 is formed by forming the placing stand 1 surface in a frame 2b or forming the placing stand 1 in a recessed surface 2a.
