CIRCUIT MODULE FOR PROTECTING A RECHARGEABLE BATTERY AND METHOD OF MANUFACTURE THEREOF

A circuit board (1) is provided upon which a predetermined number of semiconductor elements (5a, 5b, 6), including at least a field-effect transistor for charge and discharge, are mounted. A predetermined number of passive elements (7, 8a~8c, 9a~9g) are also mounted onto the circuit board. The semiconductor elements (5a, 5b, 6) are mounted facedown as bare chips on the circuit board (1).
