PROBLEM TO BE SOLVED: To provide a mold capable of bringing the whole of a parting part 8 to a close contact state by relatively small mold clamping force not only to prevent the leak of burr from the parting part 8 but also to reduce the mold clamping force of the mold 1. SOLUTION: In the mold 1 constituted by combining a plurality of split molds 2, 3 in a freely separable manner, the parting part 8 of the split molds 2, 3 is made easy to elastically deform when mold clamping force acts and, for example, in order to elastically deform the parting part 8 when mold clamping force acts, a ratio (t/L) of the width (t) to height L of the parting part 8 is set small.
