PROBLEM TO BE SOLVED: To provide both a molding method and a molding die for obtaining thin-wall moldings with good dimensional precision without causing a crack and deformation. SOLUTION: In the die for molding thin-wall moldings by using a thermosetting resin material, protrusion pins are installed in the outside periphery of a cavity and a bridging recessed part reaching the protrusion pins from the cavity is formed in the mold opening part of the die. When moldings are separated from the die, a resin part formed in the recessed part is protruded by the protrusion pins.
