PURPOSE:To prevent the erroneous insertion or erroneous charge of a button cell by providing a cell holder storing the button type cell and storing the cell holder in a cell case invariably in the normal direction only. CONSTITUTION:A button type cell 2 is stored in the recess section 3 of a cell holder 1, and the terminal 4 of the cell 2 is inserted into a small-diameter hole 5. The cell holder 1 storing the cell 2 is stored in the recess section 8 of a cell case 7 from the small-diameter hole 5, i.e., terminal 4 side. Projections 6a, 6b are provided on the opened sides of the recess section 3, the recess section 8 with nearly the same shape as the outer shape of the cell holder 1 and storing this cell holder 1 from the small-diameter hole 5 side is provided on the cell case 7. The cell holder 1 storing the cell 2 can be stored in the recess section 8 of the cell case 7 invariably in the normal direction only. |
