Winding-type coil component and direct-current superimposing circuit using the same

A winding-type coil component comprising:

• a core including a flange portion having an end surface configured for contact with a mounting surface of a circuit board and a winding core standing in a vertical direction with respect to the end surface;
• a pair of a first terminal electrode and a second terminal electrode that face each other across a winding core axis of the winding core on the end surface;
• a pair of a third terminal electrode and a fourth terminal electrode that face each other across the winding core axis of the winding core on the end surface;
• a first winding having one end portion, which is a winding start or a winding end, connected to the first terminal electrode and an other end portion, which is a winding start or a winding end, connected to the second terminal electrode;
• and
• a second winding having one end portion, which is a winding start or a winding end, connected to the third terminal electrode and an other end portion, which is a winding start or a winding end, connected to the fourth terminal electrode, the first winding and the second winding being wound around the winding core,
• wherein the second terminal electrode to which the other end portion of the first winding is connected is connected to one of a pair of differential signal lines, and
• wherein the third terminal electrode to which the one end portion of the second winding is connected is connected to an other one of the pair of differential signal lines.
