Method for manufacturing coil

Abstract

Provided is a method for manufacturing a coil enabling mass-production of good-quality coils that have an enhanced space factor in a core and enhanced heat dissipation performance and that are free from deterioration in properties due to cutting and welding. A method for manufacturing a coil includes: a step of preparing a plurality of strip-shaped flat conductors which can constitute a helical structure body when the flat conductors are continuously joined; a welding step of forming the helical structure body by butting and pressing one end face of one of the flat conductors in a strip longitudinal direction and one end face of another one of the flat conductors in the strip longitudinal direction; an annealing step of the helical structure body; an insulation step of the helical structure body; and a molding step of forming the helical structure body into a desired shape.
