Abstract
A magnetic core (50) has a core shaft part which is inserted into a bobbin part, and configures a magnetic path of magnetic flux formed by a coil (40); the magnetic core (50) is configured by combining a pair of magnetic components (51, 52); the magnetic components (51, 52) have core ends formed so as to cross a core shaft part; the base part (20) has a fitting part which fits with at least one of the pair of core ends, when the core shaft part is inserted into the bobbin part; and the coil component (100) is characterized in that the pair of magnetic components (51, 52) and the bobbin base (10) are fixed to each other, while being bound by a sheet-like fixation member (70) which extends over the core end and the base part having been fitted to each other.

A coil component comprising:
- a bobbin member having a hollow cylindrical bobbin and a bobbin base adjoining the hollow cylindrical bobbin;
- a coil wound around the hollow cylindrical bobbin;
- a magnetic core having a core shaft and a pair of magnetic components, the pair of magnetic components sandwiching the core shaft, the core shaft being inserted into the hollow cylindrical bobbin so as to configure a magnetic path of magnetic flux formed by the coil;
- and
- a sheet-shaped fixation member that fixes the bobbin member to the magnetic core,
- wherein an extending direction of each pair of magnetic components is perpendicular to an axial direction of the core shaft,
- the bobbin base has a first fitting part which fits with at least one of the pair of magnetic components when the core shaft is inserted into the hollow cylindrical bobbin,
- an upper surface of a least one of the pair of magnetic components is substantially co-planar with an upper surface of the first fitting part at an interface thereof, and the sheet-shaped fixation member extends over the interface, and
