MANUFACTURING METHOD OF SOFT MEMBER, SOFT MEMBER, MANUFACTURING METHOD OF JOINED BODY AND JOINED BODY

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a soft member capable of efficiently manufacturing a soft member that can be suitably used for manufacturing a joined body composed of a soft material in which there is no undesirable step generated at a joint of constituent members.SOLUTION: A manufacturing method of a soft member includes: a flowable material imparting step (1a) in which a flowable material is imparted to a molding tool composed of a hard material, and a first shape stabilization member composed of a hard material and having a concave-convex pattern is brought into contact with the flowable material; a solidification step (1b) in which, by solidifying the flowable material, a soft member composed of a soft material on which surface shapes of the molding tool and the first shape stabilization member are transferred is acquired; and a releasing step (1c) in which the soft member is released from the molding tool.
