PROBLEM TO BE SOLVED: To provide a PTC thermistor which can be surface-mounted as well as possess small height. SOLUTION: This PTC thermistor consists of a first and a second boards 15a, 15b, wherein a first and a second resin layers 14a, 14b having a first and a second resin layer through-holes 14c, 14d are arranged on both surfaces of a first and a second electrode layers 12a, 12b, which are arranged alternately on the upper surface and the lower surface via a polymer PTC 11, and a first and a second board penetrating holes 15c, 15d connected with the first and the second electrode layers 12a, 12b are arranged on both surfaces of the first and the second resin layers 14a, 14b. Side electrode layers 16, electrically connected with either one of the first and the second electrode layers 12a, 12b via the first and the second resin layer through-holes 14c, 14d and the first and the second board through-holes 15c, 15d, are formed on the side surfaces. |
