PROBLEM TO BE SOLVED: To provide a frame for a concrete molding which is configured of a base part and a connecting plate part and facilitates releasing of a concrete block with an L-shape section having a projecting part formed on one surface of the connecting plate. SOLUTION: In the frame for a concrete molding, a frame body for molding a surface with a formed projecting part of the connecting plate part and a surface with an upright standing connecting plate of the base part, is configured of a first frame body 8 having a projecting part molding part for molding a projecting part of a concrete molding and a second frame body 9 to be connected with the first frame body 8 in a freely separable manner. The second frame body 9 is constituted in such a way that one frame constitution part to be connected with the first frame body 8 through a connection mechanism can be released from frame and transferred leaving the other frame constitution part behind by separating the second frame body 9 from the first frame body 8. The first frame body 8 is constituted so that when the concrete molding is released from the frame by drawing the molding in the direction where the connecting plate part is projected or in the opposite direction to the former direction, one frame constitution part of the second frame body 9 is transfer-free after the release and transfer of the concrete molding by separating the first frame body 8 from the second frame body 9 and the projecting part molding part can be retreated so as not to allow itself to be an obstacle to the projecting part of the concrete molding which is transferred in the drawing direction.
