An end face of an intermediate layer of a multilayer structure is stably covered by surface resin layers at a time of cutting the multilayer structure. A cutting method of the multilayer structure includes the steps of: compressing and deforming the multilayer structure, while extending respective layers of the multilayer structure to provide a thin thickness portion, so that an upper layer bites into a lower layer by pushing a push cutter, by a predetermined amount, into the multilayer structure supported by a cutter receiving portion, in a fused state of at least one of the resin layers forming the multilayer structure; and push-cutting the compressed thin thickness portion S till the push cutter abuts against the cutter receiving portion so as to converge an intermediate layer and surface resin layers of the multilayer structure to the abutting portion A of the push cutter and the cutter receiving portion.
