Abstract: In a multilayer capacitor 1, burned layers 17A, 17B are formed so as to cover all of lead conductors 12A, 12B drawn from inner electrodes 6A, 6B to end faces of a multilayer body 2. This can keep a plating solution from infiltrating onto the inner electrodes 6A, 6B when forming plating layers 18A, 18B and prevent insulation failures from occurring. Since the burned layers 17A, 17B cover a part of dummy electrodes 13C, 13F, 13G, 13H, the area of the burned layers 17A, 17B can be suppressed. This can inhibit excessive stresses from occurring in the burned layers 17A, 17B and thus can prevent cracks from being generated by stresses in the burned layers 17A, 17B.
