PROBLEM TO BE SOLVED: To provide a fixing device for a pattern molding board of a mold, which is simple in structure and reduced in occupancy space without providing a carrier plate, to/from which a pattern molding board is attached/detached, with an attaching/detaching actuator. SOLUTION: The rotation in the clamping direction of a clamping member 20 with the spring force of a spring member 24 allows the engaging part 21 of the clamping member to be engaged with the abutting part 22 provided to the pattern molding board 3, and the pattern molding board is fixed to the carrier plate 1. The clamping member is rotated to unclamping direction against the spring force of the spring member with a pushing device 25 separately arranged with the carrier plate, then the engaged part of the clamping member is separated from the abutting part. Thereby, the pattern molding board can be surely fixed to the carrier plate in an attachable/detachable manner with a compact and simple constitution, without providing the carrier plate with an actuator.
