Zusammenfassung:	Provided is a screw fastening structure for fastening a shoulder screw to a thin metal plate member (114). Half-punched portions (141 to 144) are formed radially from a center of a through hole (115) in the thin plate member (114) by half punching so as to be alternately recessed and protruded in a circumferential direction. Further, a threaded portion (133) is formed by tapping in the through hole (115) provided at substantially the center position of the half-punched portions. Then, a member to be fastened (102) is fastened to the thin plate member (114) with a screw.
