[origin: JP2002050520A] PROBLEM TO BE SOLVED: To provide an induction microelement, provided with a magnetic core which can act at a specified high frequency. SOLUTION: In this microinductor or an induction microelement (1) such as a microtransformer, a metal winding (2) having a shape of a solenoid and a magnetic core (4) which is positioned at the center of the solenoid (2) are composed of ferromagnetic material are installed. The core (4) is constituted of a plurality of sections (13-16) which are isolated by cutouts (17-19), which are orientated perpendicular to a main axis (20) of the solenoid (2).
