ABSTRACT:
An inductance element (10) according to the present invention includes: a drum core (20) provided with an upper flange portion (21), a lower flange portion (23), a columnar leg portion (22) and a wiring frame portion (25) surrounded by the upper flange portion (21), the lower flange portion (23) and the columnar leg portion (22); a coil (40) arranged at wiring frame portion (25) and formed by winding a wire (41); and a resin curing portion (50) formed by curing a mixed material mixing magnetic powders and resin and coating at least the wiring frame portion (25) and the coil (40). In addition, a plurality of terminal members (30a,30b) as well as a bottom portion (31) and a plurality of peripheral wall portions (32) are included, in which a space portion (35) is formed between the peripheral wall portion (32) and the drum core (20), and the mixed material is filled into the space portion (35) to form the resin curing portion.
