PURPOSE:To make it possible to increase discharge capacity of power source battery in spite of thin equipment by using two or more flat type batteries as a power source. CONSTITUTION:A lower base sheet 22b of a flat type battery 30 also acts as a negative terminal plate, and a part of a positive terminal plate is extruded and forms a lead 30d'. The lead 30d' is connected to a surface part 30d'' on one side of a printed circuit board 24 and supplies electric power to, for example, an LSI chip 25a, chip components 25b, 25c, and a display panel 27. A lower base sheet 22b of a flat type battery 31 also acts as a negative terminal plate, and the battery 31 is arranged in the lower part of fixed oontact arrangement, and supplies electric power to, for example, a coil 25d. By incorporating two or more flat type batteries, electric power is separately supplied to each built-in functional element in the printed circuit board from the batteries. Since two or more batteries are incorporated, discharge capacity of the power source battery is increased as a whole. |
