There is provided a method for non-penetration joining of members. The method includes: keeping a joining member having a protruding part by a receiving mold so that the protruding part is exposed; placing a joined member over the joining member so that the protruding part of the joining member is positioned in a blind hole of the joined member, and compressing the joined member against the receiving mold to plastically deform the joined member and the joining member at the same time and to wrap excess thickness of the joined member around an undercut part while forming the undercut part on the joining member, thereby non-detachably joining both the members.
