Abstract
A method of the invention which manufactures a molded product by injection molding using injection molding die including a pair of dies includes: injecting and filling the resin in a molten state in a state where a temperature of the injection molding die is higher than a deformation temperature of resin to be injected and filled; reducing a volume of a cavity due to volume contraction of the resin when cooling thereof; and carrying out molding while maintaining a state where the resin is brought into close contact with both cavity surfaces of the pair of the dies.
