PROBLEM TO BE SOLVED: To provide an injection mold capable of preventing the formation of burrs while protecting a member to be molded. SOLUTION: In the member 2 to be molded having a recessed part 2b opened at a side surface 2a, the injection mold 1 holds the member 2 to be molded by an upper mold 12 and a lower mold 11, and a laterally moving mold 13 is brought into contact with the side surface 2a of the member 2 to be molded to almost hermetically close the recessed part 2b, and in this state, the recessed part 2b is filled with a molding resin. The lower mold 11 is formed so that the side surface 2a of the member 2 to be molded arranged on the upper placing surface 11a thereof laterally protrudes from the side surface 11e suspended from the end edge of the placing surface 11a of the lower mold 11. Furthermore, the laterally moving mold 13 is provided so as to move independent of the other mold. A compression spring 15 for laterally moving the laterally moving mold 13 to the side surface 11e of the lower mold 11 to elastically bring it into contact with the side surface 2a of the member 2 to be molded is provided.
