Abstract

A component manufacturing method includes a step of obtaining a holding tool. The holding tool includes: a frame body having an opening; and a holding film placed on the frame body. The step is a step of placing the holding film on the frame body while stretching the holding film in at least three different directions or in all directions to the frame body. The holding film includes a base layer and a holding layer. The holding tool forming device includes: a mechanism that pushes a plain film from a base layer side to bring about a stretched state; a mechanism that fixes the plain film to the frame body such that the stretched state is maintained; and a mechanism that isolates an unnecessary portion from the plain film to obtain the holding film.
