Title:
INDUCTOR
Document Type and Number:
WIPO Patent Application WO/2023/095430
Kind Code:
A1
Abstract:
The purpose of the present invention is to obtain an inductor which has a small size, can deal with a large current, and has a large coupling coefficient. This inductor (10) comprises a magnetic core (11) and a coil element (12) embedded in the magnetic core (11). The coil element (12) is composed of at least four flat plate coils in which a first coil element (12a), a second coil element (12b), a third coil element (12c), and a fourth coil element (12d) are provided in a superimposed manner. End sections of the coil element (12) each protrude from a bottom surface (11a) and are bent along the bottom surface (11a), thereby forming an external electrode (13). End sections of the first coil element (12a) and end sections of the third coil element (12c) are bent toward a first side surface (11c). End sections of the second coil element (12b) and end sections of the fourth coil element (12d) are bent toward a second side surface (11d).
