PROBLEM TO BE SOLVED: To provide a surface mounting coil which prevents the damage of an insulating material due to contact between the winding portion of a coil and its drawing portion when hot-press joining, and to provide its surface mounting coil manufacturing method. SOLUTION: The surface mounting coil 10 includes a coreless coil 20 where both ends ofαturns of a ribbon wire 12 are bent from the outermost portions 15a of the winding portion 15 to form the drawing portions 12a, 12b, a box-shaped core 25 having a recess 24, a covering core 28 fixedly bonded to its upper surface, an axial core 26 integral with the covering core 28, and terminal electrodes 29 attached to the box-shaped core 25. The surface mounting coil is constructed so that the coreless portion 18 of the coreless coil 20 is inserted into the axial core 26 holding a space S, and the ends of the drawing 12a, 12b are conductively joined on the terminal electrodes 29, 29 by hot-press, especially, the space between the drawing portion 12a, 12b and the outermost portion 15a is filled with an insulating resin 7, but the space S between the internal surrounding surface of the coreless coil 20 and the axial core 26 is not filled with an insulating resin.
