A method of forming a plating film capable of improving magnetic properties is provided. A photoresist pattern, having a first opening with an aspect ratio greater than 1 and a second opening with an aspect ratio smaller than that of the first opening, is formed on a surface of a substrate. A seed film is formed to cover an exposed surface of the substrate in the openings and an inner wall of the photoresist pattern in the openings. On the seed film in the openings, the plating film of magnetic material is deposited such that the first opening is filled under application of a magnetic field in the direction intersecting the surface of the substrate, and the second opening is filled under application of the magnetic field in the direction along the surface of the substrate.
