Patent ID: 8465011

Claim:
A fixing jig for fixing a thin plate-shaped work, the fixing jig comprising: a plate-shaped jig main body; and a close contact layer which is disposed on one surface of the plate-shaped jig main body and which detachably holds the thin plate-shaped work in close contact with the plate-shaped jig main body, wherein the plate-shaped jig main body has: a plurality of supporting projections on one surface thereof for supporting the close contact layer; and a side wall of a height which is substantially equal to the supporting projections, the side wall being disposed along an outer peripheral portion of said one surface, the close contact layer being adhered to an end surface of the side wall so as to define, between the close contact layer and the plate-shaped jig main body, a partitioned space enclosed by the side wall, wherein the plate-shaped jig main body has formed therein: a ventilation hole which is in communication with the partitioned space such that the close contact layer is deformed by suction of the air within the partitioned space via the ventilation hole; a swelled portion which swells inward of the side wall at a circumferential one side of the plate-shaped jig main body; and a suction hole which opens into an outside surface on a side of the close contact layer at the swelled portion but which is free from communication with the partitioned space, wherein the close contact layer has formed therein a through hole which is in communication with the suction hole, the through hole being so constructed and arranged that, by evacuation of the suction hole, a suction force is operated on the thin plate-shaped work.
