A method for molding a needle-equipped syringe barrel (1) by arranging an inner mold (520) of a contour corresponding to an interior contour of the inner syringe barrel (11), in which a concave portion is formed at a tip portion thereof to hold a needle rear end (122) opposite to a needle head (121), in an outer mold of a contour corresponding to exterior contours of the outer syringe barrel (1) and of an outer syringe nozzle (113). A needle (12) is kept in a region corresponding to a needle head (121) and the needle rear end (122) opposite to a needle head (121) is pressed to the concave portion of the inner mold (520) so as to prevent a material to be injection molded from flowing into a capillary of the needle (12) through the needle rear end (122).
