Abstract

The present invention provides a coil component and a method of manufacturing the same. The coil component includes an annular core, a coil wound around the core, and an electrode terminal for mounting that is connected to the coil and includes a mounting surface. A coil is formed by connecting a plurality of wire members. The electrode terminal has a recessed portion recessed toward the back surface opposite to the mounting surface. The wire member of the coil is connected to the back surface of the bottom of the recessed portion.

Description

technical field [0001] The present invention relates to a coil component and a manufacturing method thereof. Background technique [0002] Conventionally, as a coil component, there exists a coil component described in Unexamined-Japanese-Patent No. 2006-165212 (patent document 1). The coil component has an insulating base material, a core embedded in the insulating base material, a coil wound around the core, and an electrode portion connected to the coil via lead wiring. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2 006-165212 [0004] However, it has been found that the above-mentioned conventional coil component has the following problems when it is mounted on a mounting board. That is, the electrode terminals are connected to the electrode portions of the coil component, and when the electrode terminals are mounted on the mounting substrate via solder, if the solder expands or contracts due to thermal shock, the electrode terminals receive stress from th...
