Abstract:
Provided are: a coil part configured so that a winding coil can be accurately positioned relative to a magnetic core; and a method for manufacturing the coil part. A magnetic core (18) is formed by connecting in the height direction a circular column section (18a) which has an outer diameter (r1) and a circular column section (18b) which has an outer diameter (r2) greater than the outer diameter (r1). A winding coil (16) is formed by winding a conductive wire along and around the side surfaces of both the circular column section (18a) and the circular column section (18b). The outer diameter (r2) is greater than the inner diameter (R1) of the lower section (16a) of the winding coil (16), the lower section (16a) being that in which the circular column section (18a) is inserted.
