PURPOSE: A pressure distribution measurement test piece is provided to measure the parallelism between a backlight and a bonding head. CONSTITUTION: A pressure distribution measurement test piece comprises a backup plate, a settling part, test piece bodys(31,31a,32a,32b,33a,33b) and deformable parts(34a,34b,35a). The settling part is settled in the backup plate. The test piece body moves the backup plate and is pressurized with the bonding head. The deformable part interlinks the settling part and test piece body. The test piece body moves to eh backup plate by the pressurizing of the bonding head. The deformation part is transformed according to the test piece body.
