PROBLEM TO BE SOLVED: To efficiently adjust the temperature of a product cavity long in the mold body opening/closing direction by a temperature adjusting liquid passage. SOLUTION: A movable mold 1 and a fixed mold 2 being mold bodies which are mutually opened/closed and form the product cavity 3 between them when closed and a material passage 11 connected to the cavity 3 through a gate 12 are provided. The temperature adjusting liquid passage 51 surrounding the cavity 3 long in the mold body opening/closing direction is formed spirally. In the temperature adjustment of the cavity 3, by forming the passage 51, a mold can be machined easily, and efficient temperature adjustment is made possible.
