Zusammenfassung:The invention provides a coil component and an electronic device capable of suppressing extension of an external electrode to an unintended portion. A coil component (300) is provided with: a magnetic base body (10) containing metal magnetic particles formed from a soft magnetic alloy having iron as the main component; a coil conductor (30) provided on the magnetic base body (10); a glass film (50) that is provided on the surface of the magnetic base (10) and is formed from low-temperature sintered glass that contains a filler of at least one of titanium oxide, zirconium oxide, and tungsten oxide; and an external electrode (60) provided in contact with the glass film (50) and electrically connected to the coil conductor (30). 本发明提供能够抑制外部电极延伸地形成至非预期的部分的线圈部件和电子设备。线圈部件(300)包括:磁性基体(10),其包含由以铁为主成分的软磁性合金形成的金属磁性颗粒;设置于磁性基体(10)的线圈导体(30);玻璃膜(50),其设置于磁性基体(10)的表面,由低温烧结玻璃形成,低温烧结玻璃含有氧化钛、氧化锆和氧化钨中的至少一者的填料;以及外部电极(60),其与玻璃膜(50)相接触地设置,与线圈导体30电连接。
