Abstract

One object is to provide a coil element capable of enhancing reliability of joint strength of a coil conductor wire, while achieving a reduction in resistance and a size reduction. A coil element includes a core member, a coil conductor wire, and a terminal electrode. The core member has a columnar portion. The coil conductor wire has a coil portion wound on the columnar portion and a flat-shaped connection end portion provided in each of both end portions of the coil portion. The terminal electrode has an electrode layer and a joint layer. The electrode layer is formed on a surface of the core member and opposed to the connection end portion in its thickness direction. The joint layer includes a cavity portion locally provided between the connection end portion and the electrode layer and joins the connection end portion and the electrode layer to each other.
