PURPOSE:To improve user's convenience by providing an engaging part for freely drawing out a battery holder from a card substrate and preventing the detachment of the battery holder from the card substrate to the battery holder and providing a flexible jumper wire electrically connecting a battery and an electronic part between the card substrate and a printed circuit board. CONSTITUTION:When the battery holder 2 received in a card substrate 1 is drawn out, said holder 2 is not separated from the card substrate 1 because pawls 2b are provided to the battery holder 2. When the battery holder 2 is drawn out of the card substrate 1, the positive pole of the battery 3 in the battery holder 2 is connected to the pad (+)9 of a printed circuit board 8 having an electronic part mounted thereon through a battery terminal plate (+)5 and a jumper wire (+)6 and the negative pole of the battery is also connected to the pad (-)10 of the printed circuit board 8 through a battery terminal plate (-)4 and a jumper wire (-)7. Therefore, when the battery 3 is provided in the battery holder 2 even in such a state that the battery holder 2 is drawn out, the electric part built in the card holder 1 can be backed up. |
