Abstract
A film capacitor includes a capacitor element including a dielectric film and a pair of electrode layers facing each other across the dielectric film, and a pair of end-surface electrodes provided on both ends of the capacitor element. At least one electrode layer of the pair of electrode layers mainly contains aluminum and further contains zinc and magnesium. A peak of an atomic concentration of magnesium of the electrode layer is located at a position closer to a surface of the electrode layer than a peak of an atomic concentration of zinc of the electrode layer. The film capacitor has a high humidity resistance.
