An electronic component includes a magnetic body having internal coil patterns. The magnetic body includes a core part including the internal coil patterns; and upper and lower cover parts disposed above and below the core part, respectively. Magnetic wires are disposed in the core part, and magnetic plates are disposed in the upper and lower cover parts.

The magnetic sensor comprises a magnetic wire rod that generates a large Barkhausen effect, a coil, and a bobbin; the bobbin has a wire winding portion in whose interior the magnetic wire rod is disposed and on whose outer peripheral portion the coil is provided, and a pair of columnar support portions respectively provided in the sections at opposite ends of the wire winding portion; the pair of columnar support portions protrude downwardly from the respective sections at opposite ends of the wire winding portion; and the amount of protrusion thereof is configured such that, once the magnetic sensor is mounted to the substrate, a component placement space allowing for placement of components is formed between the section on the outer peripheral surface of the coil facing the component-carrying surface and the component-carrying surface itself.
