Abstract: An inductor includes a body that includes a coil and that contains a magnetic portion in which the coil is embedded, and a pair of outer electrodes that is disposed on a mounting surface of the body. The coil includes a winding portion formed by winding a conductive wire that has a coating layer and that has a pair of wide surfaces, and a pair of extended portions that extends from the winding portion. The pair of extended portions includes a twisted portion that is connected to the winding portion. The twisted portion is twisted about a virtual center line of an end portion of the winding portion, and a twisted part bends toward the mounting surface about an axis substantially perpendicular to the wide surfaces at the end portion. End portions of the pair of extended portions near the mounting surface are connected to the pair of outer electrodes.

One wide surface of a distal end portion of the second lead-out portion is exposed at the mounting surface, a second surface adjacent to the mounting surface, and a corner portion therebetween. The outer electrodes cover the exposed wide surfaces of the first and second lead-out portions.
