Claims

[Scope of utility model registration request]

In a fixed inductor, a drum core around which a coil is wound is placed on a substrate on which external terminals are fixed, and a cap core that covers the coil is arranged above the drum core. A first engaging portion is formed on one of the two, a second engaging portion is formed on the other, and an insulating member is formed between the first engaging portion and the second engaging portion. A fixed inductor having a structure in which a holder is interposed, and the first engaging part and the second engaging part are engaged with each other via the holder.
