There is provided a male engaging member of a surface fastener comprising novel engaging elements that are flexible to a certain extent and highly durable and, at the same time, ensure a certain level of peeling resistance. The engaging elements of such an engaging member stably remain in engagement with piles of a female engaging member coupled with it without unintentionally becoming disengaged from the piles caught by them. The engaging miember comprises a flat substrate sheet, first engaging elements having a stem and an engaging portion disposed at the top thereof and second engaging elements having a column portion and a tilted hitch portion also disposed at the top thereof, the first engaging elements and the second engaging elements being arranged in linear rows independently relative to each other. The height of the second engaging elements as measured from the surface of the substrate sheet to the top thereof is about twice as large as the height of the first engaging elements from the bottom to the top thereof. All the hook-shaped engaging portions and all the tilted hitch portions extend in the same direction in one row, the direction being opposite to the extending direction in adjacent rows.
