PROBLEM TO BE SOLVED: To provide a manufacturing method of a battery pack, in which a battery pack which has a high dimensional accuracy and strength and has a small size and a light weight can be manufactured with a high productivity. SOLUTION: The battery pack is provided with a battery 20 in which a battery element 10 wound by a positive electrode 11 and a negative electrode 12 with a separator 13 in-between is covered by a laminated film 17, a protecting circuit board 32 of the battery 20 and an external covering material 18 which covers integrally the battery 20 and the protecting circuit board 32 while a terminal 15 of the battery 20 is extruded out by being filled in and hardened in a formed mold C which houses the battery 20 and the protecting circuit board 32, and moreover is provided with spacers 35 which set up the battery 20 and the protecting circuit board 32 at a predetermined position in the formed mold C and are integrated with the external covering material 18 which is filled in and hardened in the mold C. The spacers 35 are arranged so that the external covering material 18 can be spread over a whole of a surrounding space of the battery pack 20 and the protecting circuit board 32.
