PROBLEM TO BE SOLVED: To provide a shaping mold capable of increasing tenacity of a surrounding portion of a hole formed by an insert member and preventing crack generation. SOLUTION: When a biodegradable resin filling a cavity 21 is molten at a relatively high temperature, a screw insertion hole shaping pin 17 is inserted in the cavity 21. By this the biodegradable resin collides with itself behind the screw insertion hole shaping pin 17 in the cavity 21 to prevent a weld line having a small fusion area or weak tenacity from being formed.
