[Problem] To prevent peeling of a terminal electrode from a base portion and to improve precision in assembling a terminal electrode on a base portion. [Solution] Provided is a coil component comprising: a base portion having a first surface and a second surface connected to the first surface, a first virtual plane including the first surface and a second virtual plane including the second surface intersecting at an obtuse first angle; a coil portion formed by a conductor wound around the base portion; and a first terminal electrode connected electrically to the coil portion, the terminal electrode being made of a plate-shaped first metal plate having a first portion fixed to the first surface of the base portion by a first bonded portion, and a second portion bent towards the first portion and coming into contact at the leading end with the second surface of the base portion.

Coil component, electronic device, and coil component manufacturing method

An electronic component includes a member with marking having at least one marking area to be processed digitally, as well as a member other than the member with marking. The marking allows for tracing the production history of individual electronic components.

Electronic passive component having marking area for tracing production history

In an embodiment, a coil componenthas a drum corehoused in a through holeof a ring core, and two types of securing parts are provided in a gap G between an outer circumference of one flange partof the drum coreand an inner circumference of the through hole. Terminal electrodesA,B connecting to endsA,B pulled out from a winding wirewound around the drum coreare assembled to the ring core. Second securing partsA,B are arranged to opposite to each other with respect to a center C of the flange part, and first securing partsA,B are provided to cover an outer side of the second securing partsA,B. A hardness of the second securing part is higher than that of the first securing part.
