[Problem] To provide technology that can increase the productivity of an apparatus when magnetron sputtering is carried out using a target formed from magnetic material. [Solution] The present invention is an apparatus constituted so as to be provided with: a cylindrical body that is a target formed from magnetic material, disposed above a substrate such that the center axis thereof is offset from the center axis of the substrate in a direction along the surface of the substrate; a rotating mechanism that rotates this cylindrical body around the axis of the cylindrical body; a magnet array provided inside a hollow part of the cylindrical body; and a power supply that applies voltage to the cylindrical body. Furthermore, the magnet array has a cross sectional profile, orthogonal to the axis of the cylindrical body, such that the center part protrudes more to the peripheral surface side of the cylindrical body than both end parts in the circumferential direction of the cylindrical body. Thus, even if a target with a comparatively large thickness is used, reductions in the intensity of the magnetic field that leaks from the target can be suppressed, and local progress in erosion can be suppressed.
