PURPOSE:To obtain a thin compact circuit assembled with a usual metal piece for electrode by folding a flexible circuit board on which a conductive pattern is formed so that the conductive pattern locates inside. CONSTITUTION:Circuit components such as capacitors, resistors, and transistors are mounted on one side of a flexible circuit board 5 on which a conductive pattern is formed. The flexible circuit board is folded so that the component mounted surface locates inside, and a coin type battery 6 is placed between the folded surfaces. Terminal metal plates 7a and 7b are connected to positive and negative electrodes of the battery 6 respectively so that the plates are in parallel, and the other ends of the metal plates are soldered to the conductive pattern on the folded flexible circuit board 5. |
