A jig for heat treatment of a workpiece capable of use over a long period of time by minimizing or eliminating deformation thereof caused by thermal distortion and which is capable of performing heat treatment of the workpiece by reducing the amount of heat energy absorbed by the jig in a heat-treatment furnace. The jig includes an outer peripheral frame formed by a plurality of members and a mounting portion arranged inside the outer peripheral frame and also formed by a plurality of members. The workpiece rests on the mounting portion during use. The members of the outer peripheral frame and mounting portion are movably connected to each other with an expansion space being provided between each adjacent member capable of absorbing thermal expansion of the member during thermal treatment.
