发明名称 SEMICONDUCTOR PORCELAIN COMPOSITION, POSITIVE TEMPERATURE COEFFICIENT ELEMENT, AND HEAT-GENERATING MODULE
摘要 The present invention provides a semiconductor ceramic composition which is represented by a composition formula of [(Bi-A) x (Ba 1-y R y ) 1-x ](Ti 1-z M z ) a O 3 (in which A is at least one kind of Na, Li and K, R is at least one kind of rare earth elements (including Y), and M is at least one kind of Nb, Ta and Sb), in which a, x, y and z satisfy 0.90‰¤a‰¤1.10, 0<x‰¤0.30, 0‰¤y‰¤0.050 and 0‰¤z‰¤0.010 and an average distance between voids, which is an average value of a space between voids being internally present, is 1.0 µm or more and 8.0 µm or less.
