Surface-mount inductor

摘要

[TECHNICAL PROBLEM] The present invention provides a surface-mount inductor allowing the Q to be improved at a higher frequency and preventing the efficiency of the inductor from getting worse even at the higher frequency. [SOLUTION TO THE PROBLEM] A surface-mount inductor comprises: a coil formed by winding a conductive wire; and a core containing the coil and formed by subjecting a mixture of a magnetic powder and a binder to powder-compacting. The magnetic powder contains plural types of magnetic powders each having a different particle size from the other, and the plural types of magnetic powders are mixed to satisfy the following relationship: £an · ¦n ‰¤ 10 µm, where an is a mixing ratio, ¦n is an average particle size, and n is an integer of 2 or more.
