Combined coil module and magnetic sheet

A combined coil module is provided with a first flat coil, a second flat coil, and a magnetic sheet in which a magnetic circuit of the first flat coil and a magnetic circuit of the second flat coil are formed. The first flat coil is used in wireless communication. The second flat coil is used in power transmission for non-contact charging. The magnetic sheet comprises one type of magnetic body. The magnetic sheet has a first magnetic circuit formation section in which the magnetic circuit of the first flat coil is formed, and a second magnetic circuit formation section in which the magnetic circuit of the second flat coil is formed. The magnetic permeability of the first magnetic circuit formation section differs from the magnetic permeability of the second magnetic circuit formation section. 复合线圈模块具备第1平面线圈、第2平面线圈和形成第1平面线圈的磁路以及第2平面线圈的磁路的磁性片。第1平面线圈用在无线通信中。第2平面线圈用在非接触充电的电力传送中。磁性片包含一种磁性体。磁性片具有形成第1平面线圈的磁路的第1磁路形成部、和形成第2平面线圈的磁路的第2磁路形成部。第1磁路形成部的导磁率与第2磁路形成部的导磁率不同。
