Patent number: 7009485Abstract: A laminate-type electronic component includes has a first coil and a second coil, and the number of turns of the first coil is smaller than that of the second coil due to a positional relationship between input-output electrodes. As a result, the thickness of an outer layer on the first coil side is increased, that is, the magnetic path cross-sectional area of the outer layer is increased. Thus, the inductance of the first coil is decreased. The thickness of the outer layer on the second coil side is decreased, that is, the magnetic path cross-sectional area of the outer layer on the second coil side is decreased. Thus, the inductance of the second coil is decreased.Type: GrantFiled: November 12, 2004Date of Patent: March 7, 2006Assignee: Murata Manufacturing Co., Ltd.Inventors: Takashi Tomohiro, Hiromichi Tokuda, Yoshihiro Imanishi
