In a molded surface fastener ( 10 ) having engaging elements ( 2 ) of minute dimension of thermoplastic resin molded together with a base member ( 1 ) by continuous molding, each engaging element ( 2 ) comprises first and second engaging portions ( 22 a, 22 b) each having a different configuration extending in parallel to a surface of the base member from a top end of a pillar portion ( 21 ) rising from the base member ( 1 ) such that they intersect at right angle. The second engaging head ( 22 b) has an ordinary hook shape structure while the first engaging head ( 22 a) has a wing-like thin plate structure as seen in a plan view. The engaging elements having such a structure in which each engaging element has appropriate engagement force, shearing force and separation force so as to keep an excellent tactile feeling of a surface of the surface fastener, prevents itself from falling down against a pressing force, secures a high engagement ratio with mating pile pieces and satisfies a durability.
