Abstract: A resin casting mold includes a cavity having a predetermined shape and is used for producing a molded resin product by transferring the shape of a surface on the cavity side of a mold member forming the cavity to a resin material. The surface on the cavity side of the mold member includes first and second surfaces facing each other in a first direction and each of the first and second surfaces have a predetermined surface shape, the mold member includes an insert member which forms a part of a third surface different from any one of the first and second surfaces of the surface on the cavity side and which is slidable in a second direction perpendicular to the first direction, at least one cross-sectional shape of the cavity satisfies a relation h
