Abstract
An electric circuit-use core which has low loss, is less susceptible to magnetic saturation, thus allows for size reduction and current increase, and has a wide operation range in high-frequency region, and a manufacturing method for the core are provided. The electric circuit-use core is a dust core formed by compression molding or injection molding with an iron-based amorphous material, a cobalt-based amorphous material, or a sendust material as a magnetic material, and is used as a transformer core, a choke core, or a core of a reactor. The electric circuit-use core includes cylindrical pillar portions and connection portions.
