INDUCTANCE ELEMENT, METHOD FOR MANUFACTURING THE SAME, AND SWITCHING POWER SUPPLY USING THE SAME |
摘要 |
An inductance element (1) includes a doughnut-shaped magnetic core (2) having a wound body or a stacked body of a magnetic ribbon, a bottomed container (3) in which the doughnut-shaped magnetic core (2) is housed, and a conductive lead portion (5) inserted into a hollow section of the doughnut-shaped magnetic core (2) housed in the bottomed container (3). An open section of the bottomed container (3) is covered with an adhesive portion (4) which integrally fixes the doughnut-shaped magnetic core (2), the bottomed container (3) and the conductive lead portion (5). The adhesive portion (4) is entered into a gap between the doughnut-shaped magnetic core (2) and the bottomed container (3) and a gap between the bottomed container (3) and the conductive lead portion (5) in a range of 5 to 50% in average to a thickness of the doughnut-shaped magnetic core (2).
