摘要：
An inductance element (1) includes a doughnut-shaped magnetic core (2) and a bottomed container (3) for housing the doughnut-shaped magnetic core (2). The bottomed container (3) has a cylindrical outer wall portion, a cylindrical inner wall portion, a bottom portion, an open section and a hollow portion. The open section of the bottomed container (3) is covered with an adhesive portion (4) for integrally fixing the doughnut-shaped magnetic core (2) and the bottomed container (3). The adhesive portion (4) has an extended portion (4a) extended in the cylindrical inner wall portion. The ratio (B/A) of a length (B) of the extended portion (4a) to a height (A) of the cylindrical inner wall portion is in a range of 0.1 to 0.5.
