摘要： A common mode choke coil includes two extraction conductors formed on a resin insulating layer, and a concave portion is formed in the resin insulating layer in an area between a first portion covered with one of the extraction conductors and a second portion covered with the other extraction conductor. An upper resin insulating layer is embedded inside the concave portion. Accordingly, because the resin insulating layer is not flat in the portion where the extraction conductors are formed, a distance between the extraction conductors along the surface of the resin insulating layer increases. Therefore, a current path generated due to ion migration along the surface of the insulating layer is hardly formed, thereby enabling to obtain high withstand voltage, even if the distance between the extraction conductors is short.
摘要翻译：共模扼流线圈包括形成在树脂绝缘层上的两个引出导体，并且在树脂绝缘层之间的一个区域中形成凹部，该第一部分覆盖有一个引出导体，第二部分覆盖有另一个提取导体。上部树脂绝缘层嵌入凹部内。因此，由于树脂绝缘层在形成提取导体的部分中不是平坦的，所以提取导体之间距树脂绝缘层表面的距离增加。因此，由于沿着绝缘层的表面离子迁移而产生的电流路径几乎不形成，因此即使提取导体之间的距离短，也能获得高的耐受电压。
