To provide a manufacturing method of an inductor, allowing for suppression of formation of a gap between adjacent wiring in a magnetic layer, thereby allowing for suppression of variation in distance between adjacent conductors.SOLUTION: A manufacturing method of an inductor 1 comprises a first step of preparing a hot press apparatus 2 and a second step. The hot press apparatus 2 comprises: a first die 3; a second die 4 which is disposed with a gap interposed between the first die 3 and the second die 4, and which is smaller than the first die 3; and an inner frame member 5 which surrounds a circumference of the second die 4, is disposed with a gap in a press direction interposed between the first die 3 and the inner frame member 5, and which can move in the press direction to the second die 4; and a flowable soft sheet 6 arranged on a second press surface 62 of the second die 4. In the second step, a magnetic seat 8 containing a magnetic particle and a thermosetting resin, and a plurality of wiring 9 which are separated from each other at an interval are hot-pressed by the hot press apparatus 2.SELECTED DRAWING: Figure 2
