PURPOSE: To provide a manufacturing method of click boards or movable contactor made of resin by which a large number of uniform click boards or movable contactors are manufactured easily.

CONSTITUTION: A prescribed part of a strip-like film 1 made of synthetic resin is put between an upper die and a lower die. The film 1 is sandwiched between the upper die and the lower die, heated and pressed to deform the part at the prescribed position of the sandwiched film 1 and thus a click board 13 (or a movable contactor) is processed. The circumference of each processed click board 13 (or each movable contactor) is trimmed while the connecting part 17 of the film 1 is left. A large number of click boards 13 (or movable contactors) are continuously formed from the film 1 by repeating each of these processes continuously.
