PROBLEM TO BE SOLVED: To provide a mold capable of preventing the occurrence of a weld line. SOLUTION: The confluent part A forming a place where molten resins strike with each other in a cavity 8 is heated from the cavity plate 3 being one mold from forming the design surface of a resin product by a heating means 13 and a degassing core 14 is embedded in a core plate 4 so as to be exposed to the inner surface of the cavity 8 in the vertical direction of the confluent part A to be discharged from the air in the cavity 8 or the gas produced from the raw material from the fine gap C formed between a square hole 4c and a first degassing core 14a, the fine gap C formed between the square hole 4c and a second degassing core 14b, the fine gap C formed between the first degassing core 14a and the second degassing core 14b and the fine gap C formed between the first degassing core 14a and an ejector pin 10.
