Abstract: A caulking jig comprises a main body, a blade portion having a blade edge, a projection member fit in the main body, an urging member which urges the projection member, and an engagement mechanism configured to engage the projection member to the main body. In a state in which the projection member is not engaged, the projection member is held at a projected position where a distal end portion of the projection member is projected from the blade edge. In a state in which the projection member is engaged, the projection member is held at an entered position where the distal end portion is retracted to a more entered position than the blade edge.

Abstract: A film forming method of forming a film by accelerating powder of a material with gas and spraying and depositing the powder onto a surface of a substrate with the powder being kept in a solid state includes: a substrate film forming step of forming a film. The film forming step includes jetting out the powder and inert gas from a nozzle towards the substrate, causing inside of the chamber to be under positive pressure by the inert gas, and depositing the powder on the surface of the substrate.
