PURPOSE:To prevent occurrence of inoperation or malfunction due to improper contact by inserting a battery while the distance of opposite contacts of a terminal board is widened. CONSTITUTION:A battery holder 2 is integrated with a cap 22 and a support frame 23 and the support frame 23 is so structured that two batteries 6 stacked are inserted from the side and electrodes of both sides are exposed. When the holder 2 is inserted from the end of a case main body, the supported batteries 6 are inserted while extending contacts 52b, 53b, the contact face is wiped out to clean the surface, terminal boards 52, 53 and the batteries 6 are surely in contact with each other and excellent contact is kept for a long period. Moreover, intermediate parts 52c, 53c are abutted on an inner case 11, then a stress at deformation is not directly transmitted to bases 52a, 53a and no excess force is exerted to a soldered part of a printed circuit board 5.
