In this molded surface fastener, an engaging element includes a columnar stem portion, and micro pawl portions protruding outward from an upper end outer peripheral edge of the stem portion in a plan view of the engaging elements. A pawl width dimension of the micro pawl portions is smaller than a line segment connecting two points on the upper end outer peripheral edge of the stem portion. The micro pawl portions protrude toward a base portion. This molded surface fastener has a high peel strength and a shear strength with respect to a female surface fastener.
