简介 There is provided a semiconductor ceramic composition in which a portion of Ba of BaTiO 3 is substituted by Bi-Na, which exhibits an excellent jump characteristic while reducing room temperature resistivity and which also reduces room temperature resistivity and exhibits small change with time. A semiconductor ceramic composition which is represented by a composition formula of [(Bi ¸ -Na ´ ) x (Ba 1-y R y ) 1-x ]TiO 3 (where R is at least one kind of rare earth elements), in which x, y, ¸ and ´ satisfy 0
