PROBLEM TO BE SOLVED: To provide a coil part having enhanced mounting strength, proper mounting accuracy and proper Q characteristics. SOLUTION: On the outer surface of a sword-guard part 15, a terminal electrode 40 constituted of: a bottom electrode 41A provided, by burning Ag into a pair of sword-guard parts 15 in the axis direction of a winding core part 11, the entire surface of a bottom face 20 forming an edge surface of each sword-guard part 15 and the entire surface of a second side face 17; and a top electrode 41B, produced by laminating an Ag layer and an Ni layer, in this order, by dipping on the entire surface of the bottom electrode 41A and by plating Sn on the entire surface of the Ni layer, is provided. A part of the bottom electrode 42A that forms part of a mounting-face opposite part 42 of the terminal electrode 40 has a conductor connecting region which is a region where a copper wire, constituting one terminal 30A and another terminal 30B of a winding 30, is respectively fixed by thermocompression bonding to be connected electrically, and one terminal 30A and the other terminal 30B are covered with the top electrode 41B.
