摘要： A problem to be solved is to stabilize temperature characteristics in various characteristics of a magnetic element. A magnetic element has a coil formed by winding a conductor, EP cores constituted of a magnetic material and passing magnetic flux generated in the coil, a solid part provided between EP cores opposing each other among the EP cores, and having a ceramics material or a resin material, in which the solid part is in contact with opposing faces of the respective opposing EP cores, and the solid part is provided with a thickness dimension ranging from 3 μm to 30 μm.
摘要翻译：要解决的问题是稳定磁性元件的各种特性中的温度特性。磁性元件具有通过缠绕导体形成的线圈，由磁性材料构成的EP磁芯和在线圈中产生的通过磁通，设置在EP磁芯之间彼此相对的EP磁心之间的实心部分，并且具有陶瓷材料或树脂材料，其中固体部分与各个相对的EP芯的相对面接触，并且固体部分设置有3μm至30μm的厚度尺寸。

摘要： A transformer-type compact and thin coil device having a high coupling degree between a primary coil and a secondary coil, and a transformer device in which a plurality of sets of the transformer-type coil devices are incorporated. A coil device includes a first winding portion in which a primary and secondary coil wires are wound in bifilar form so as to arrange them alternately in a plane, a second winding portion in which a secondary coil wire is wound to arrange it in a plane parallel to the plane of the first winding portion, and a secondary coil connecting portion which connects an inner diameter portions of the secondary coil wires of the first and second winding portions. A transformer device is formed by incorporating a plurality of sets of the transformer-type coil devices each formed in above manner.
