Coil device

The present invention provides a coil device mountable on a circuit board, comprising: a coil provided with a winding portion and a winding lead wire led out from the winding portion; and a terminal block provided with an insulating main body part and a lead wire held by the main body part. Furthermore, the lead wire includes: a bottom-surface-side terminal protruding from a bottom surface of themain body portion facing the circuit board and connectable to the circuit board; and a side surface-side terminal that protrudes from the side surface of the main body in a direction different from the protruding direction of the bottom surface-side terminal and is connected to the end of the winding lead wire. The coil device is capable of ensuring an insulation distance between an end portion ofa coil connected to a side surface side terminal and a circuit board. 本发明提供一种能够安装于电路板的线圈器件，其包括：线圈，其设有绕阻部和从绕阻部引出的绕组引出线；端子座，其设有具有绝缘性的主体部和由主体部保持的引线。另外，引线包括：底面侧端子，其从与电路板相对的主体部的底面突出，且能够与电路板连接；侧面侧端子，其从主体部的侧面向与底面侧端子的突出方向不同的方向突出，且与绕组
