To realize the sure molding of a concrete molding and to improve its durability by a method wherein the sealing properties between the concrete molding and its adjacent mold and prevent a gap, which gives hindrance to the molding of the surface of the concrete molding due to the separation of a flexible mold body from a surrounding frame, from developing.

This surface mold H of a concrete molding is equipped with a surrounding frame 12 along the outer peripheral edge part on the front surface side of a panel 10 and formed by annexing a flexible mold 13 for molding the surface of the concrete molding by being cast under fluid state to the front surface side of the panel 10 and solidified. The upper end edge part and outer surface of the surrounding frame 12 are covered with the flexible mold body 13 so as to form a covering part 14 abutting against an adjacent lower mold 5 and edge face molds 7 under the condition that the upper end edge part of the surrounding frame 12 is made into an uneven part and through holes are formed in the surrounding frame 12.
