PURPOSE:To obtain a thin electronic circuit unit having high packaging density by electrically connecting card-shaped batteries whose one whole surface is a positive electrode and the other is a negative electrode by facing the same polarity of each battery. CONSTITUTION:A battery 4 is formed in a card shape and its thickness is less than 1mm, for example. One whole surface of the battery is a positive electrode and the other is a negative electrode. Positive electrodes of the two card-shaped batteries 4 are faced each other and pressed against a conductive metal thin plate 6 which is inserted between these positive electrodes. One end of a lead 7 is connected to the metal thin plate 6, and other end of the lead 7 is electrically connected to a PCB. Negative electrodes of both batteries are connected with a conductive fitting 8. An electronic circuit unit with card-shaped batteries 4 has high packaging density. |
