Patent number: 9039859Abstract: A ceramic green sheet laminate is produced by stacking ceramic green sheets, each including conductive films for forming first or second internal electrodes on a surface thereof. A first cutting step is performed in which the ceramic green sheet laminate is cut to form first and second end surfaces at which the first or second internal electrodes are exposed. A second cutting step is performed in which the ceramic green sheet laminate is cut to form first and second side surfaces at which the first and second internal electrodes are exposed. In the second cutting step, the ceramic green sheet laminate is pressed and cut by moving a cutting blade in a length direction or a width direction.Type: GrantFiled: February 5, 2013Date of Patent: May 26, 2015Assignee: Murata Manufacturing Co., Ltd.Inventors: Junya Tanaka, Hironori Tsutsumi
