To provide an inductor and a mounting structure thereof that can handle high temperature and large current.SOLUTION: A first collar portion 15 of a core 12 is provided with first and third terminal electrodes 17 and 19, and a second collar portion 16 of the core is provided with second and fourth terminal electrodes 18 and 20. First and second wires 25 and 26 are wound around a winding core 13 in directions opposite to each other. The first and second terminal electrodes 17 and 18 are diagonally opposed, and the third and fourth terminal electrodes 19 and 20 are diagonally opposed. One end 25a of the first wire 25 is connected to the first terminal electrode 17, and the other end 25b is connected to the second terminal electrode 18. One end 26a of the second wire 26 is connected to the third terminal electrode 19, and the other end 26b is connected to the fourth terminal electrode 20. A current flows from a conductor commonly connecting the first and fourth terminal electrodes 17 and 20 toward a conductor commonly connecting the second and third terminal electrodes 18 and 19.SELECTED DRAWING: Figure 1 【課題】高温・大電流に対応可能なインダクタおよびその実装構造を提供する。【解決手段】コア１２の第１鍔部１５には、第１および第３端子電極１７，１９が設けられ、第２鍔部１６には、第２および第４端子電極１８，２０が設けられる。巻芯部１３のまわりには、第１および第２ワイヤ２５，２６が互いに逆まわり方向に巻回される。第１および第２端子電極１７，１８は対角線方向に対向し、第３および第４端子電極１９，２０は対角線方向に対向する。第１ワイヤ２５の一方端末２５ａは第１端子電極１７に接続され、他方端末２５ｂは第２端子電極１８に接続される。第２ワイヤ２６の一方端末２６ａは第３端子電極１９に接続され、他方端末２６ｂは第４端子電極２０に接続される。第１および第４端子電極１７，２０を共通に接続する導体から、第２および第３端子電極１８，１９を共通に接続する導体に向かって電流を流す。【選択図】図１
