The invention provides a coil device 1 capable of preventing a short-circuit fault. The coil device 1 has a core 10 including a winding core portion 12 and a flange portion 14 formed on an X-axis-direction end portion of the winding core portion 12, a coil portion 30 formed by wires 31,32 being wound around the winding core portion, and terminal electrodes 41,42 provided on the flange portion. Leadout portions 310,320 of the wires are respectively connected to the terminal electrodes. A main protuberance 144 having a protuberating shape is formed on an upper surface 14a of the flange portion.A second lead-out section (320) of the second wire (32) is connected to the second terminal electrode (42) on the outside in the X-axis direction of the main protrusion (144). 本发明提供一种能防止发生短路故障的线圈装置(1)，包括：芯(10)，其包括卷芯部(12)和形成于卷芯部(12)的X轴方向上的端部的凸缘部(14)；将线(31、32)缠绕于卷芯部(12)而形成的线圈部(30)；和设置在凸缘部(14)上、供线(31、32)的引出部(310、320)分别连接的端子电极(41、42)。供端子电极(41、42)的至少一部分配置的凸缘部(14)的上表面(14a)上，形成有具有隆起形状的主隆起部(144)，第二线(32)的第二引出部(320)在相比主隆起部(144)靠X轴方
