Abstract
A method of processing a composite member having a structure in which a first member having a separation layer inside is brought into tight contact with a second member. The composite member has a projecting portion at which a peripheral edge of the first member projects outside a peripheral edge of the second member. The method includes a detection step of detecting the projecting portion of the composite member using a sensor and a separation step of starting separating the composite member from the projecting portion detected in the detection step and then separating the composite member into two members at the separation layer.
