An efficiency is further improved in comparison with a conventional manual operation by automatically applying a material to a film-like body by a machine. A film-like body is delivered from a supply apparatus and is taken up by a take-up apparatus. A material is applied by a squeegee of a squeegee apparatus in the middle of the above, and is heated and dried by a reflow apparatus and an application of the material is executed by a rotation of a screen mask supported to a mask support body in a cylindrically wound state in correspondence to a moving speed of the film-like body, a slidable contact of the squeegee of the squeegee apparatus installed in an inner portion of the screen mask with an inner surface of the screen mask, and a downward extrusion of the material.
