PROBLEM TO BE SOLVED: To provide a side gate type injection molding mold for inhibiting generation of a weld line generated on a molded part made from a resin material which is loaded with a luminosity material, and for improving defective appearance. SOLUTION: The side gate type injection molding mold includes a product section 7 which is a space for molding, and a side gate 8 for injecting a material into the product section 7, in which the side gate 8 is formed so as to have an approximately quadranglular cross-section at a contact part 9 of the product section 7 and the side gate 8, wherein at least one of edge regions 9e of the cross-section formed at the contact part 9 of the side gate 8 is formed in a curvature configuration, and a resin material which is loaded with a luminosity material is injected from the side gate 8 into the product section 7 to produce a molded part 1.
