PROBLEM TO BE SOLVED : To provide a laminated varistor, in which the grain growth of the outer peripheral part of a laminated varistor can be suppressed, characteristic deterioration in a characteristic part due to the outer peripheral part can be prevented, and failures such as the mutual welding of laminates at burning can be prevented. SOLUTION : This is a laminated varister 1, in which ceramic layers 5 with ZnO as the main component and inside electrode layers 13 formed on the ceramic layers 5 are laminated on a laminate, and outside electrodes 17 are formed so as to be electrically connected with the inside electrode layers are formed on the laminate. The ceramic layers on which the inside electrode layers 13 are formed are constituted of characteristic parts 9 with varistor characteristics and outer peripheral parts 11 other than the characteristic parts, and at least one kind of oxide or compound selected from among Y, Ba, Sr, and rare earth elements are present in the outer peripheral parts 11. |
