PROBLEM TO BE SOLVED: To provide a surface mounting inductor without polarity capable of reducing thermal stress and mechanical stress to a coil and eliminating contact resistance generated between the coil and an external terminal, in a surface mounting inductor that incorporates the coil in an element assembly having a magnetic body, and to provide a method of manufacturing the same.SOLUTION: A surface mounting inductor comprises a coil 2, and an element assembly that incorporates the coil. The coil comprises: a first wound part 2c wounded with a lead wire having a rectangular cross section; a second wound part 2d wound so as to be shifted to a position adjacent to the first wound part along a winding axis; and a third wound part 2e wound so as to be shifted to a position in an opposite direction to the first wound part along the winding axis and so as to be partially overlapped with the second wound part. End parts of the lead wire are led out from an outer periphery of the first wound part and an outer periphery of the third wound part, and set as lead-out end parts 2b. The winding axis is parallel to the mounting surface of the element assembly, and a surface of the lead-out end part is extended to a surface of the mounting surface of the element assembly.SELECTED DRAWING: Figure 1 |
