A movable member is gripped in a delamination-start configuration, and the other-end side of a rib of a delamination member is pressed towards the other-end side of a flexible plate. The flexible plate then warps and deforms about the other end side of the flexible plate, which is supported by a support member, the flexible plate deforming along the direction in which delamination progresses. In concert with the delamination action, a reinforcing plate also warps and deforms along with the flexible plate, the reinforcing plate being vacuum-chucked to an air-permeable electroconductive sheet on the flexible plate, and the reinforcing plate is sequentially delaminated from a substrate 2 along the direction in which delamination progresses.
