摘要：
When a plurality of ceramic green sheets provided with cavity holes are respectively pressed by an elastic member, rigid plates which are sized to be in contact with overall major surfaces of the respective ceramic green sheets and provided with holes equivalent to or slightly smaller than the cavity holes are interposed between the elastic member and the respective ceramic green sheets. Thus, the cavity holes are inhibited from undesired deformation caused by deformation of the elastic member.
