PROBLEM TO BE SOLVED: To provide a manufacturing method of a battery pack capable of preventing increase of the number of components while preventing a short circuit of an electronic component of a circuit board due to dust, damage of the electronic component or the like of the circuit board and a battery short circuit in die insertion of a core pack, and capable of relatively easily manufacturing the battery pack. SOLUTION: Before a frame 3 made of a synthetic resin integrally molded with a unit cell 2 is molded, a circuit module 13 composed by entirely covering, with a synthetic resin, the circuit board 16 with ICs and the like mounted is previously formed. After the circuit module 13 is disposed on the front side of the unit cell 2, the frame 3 is molded with the circuit module 13 covered with the synthetic resin. COPYRIGHT: (C)2004,JPO&NCIPI
