Zusammenfassung:PROBLEM TO BE SOLVED: To provide a choke coil that can be preferably applied to automated mounting by permitting correct positioning in component mounting and stabilizing a soldered connection accommodating high current.SOLUTION: A wire rod 2 is wound around a bar-shaped ferrite core 1 as prescribed to form a coil 3, and the wire rod 2 is provided with a current capacity increased by an increased wire diameter or the like to accommodate application to high current. Two electrode pieces 4 are supported in a spaced parallel state on an upper surface of a support 5. The ferrite core is vertically arranged with an end face fixed to the two electrode pieces. The electrode pieces each comprise a strip of sheet metal cranked in multiple stages to have flat portions respectively outside a lateral side opposed to the support, and a tip end of one flat portion is bent upward into a raised edge portion 44, which is provided with a hole portion 43. The flat portions are terminal portions 42 capable of contacting with pattern portions of a printed board, and lead ends 31 of the coil are fitted in the hole portions to establish electrical connection.
