To provide an anchor pin which can be easily manufactured and can exhibit high pull-out resistance. An anchor pin includes an elongated pin main body (10) provided with a tip (12) at a tip end of a shaft (11), and a withdrawal resistant wing (20) attached near the pointed part of the axle. Are connected to the outer periphery of the shaft part, two front wing parts 22 extending from the connection part to both sides of the shaft part, and extending from the two front wing parts to the rear end side of the shaft part, respectively. And two wing tail portions 23 that protrude, and the two wing tail portions are inclined in opposite directions with respect to the two front wing portions.
