摘要：Provided is a ferroelectric ceramic material containing BaTiOas a maincomponent which can control a Curie temperature in a wide range, has no phasetransition in the vicinity of a room temperature, and exhibits excellent ferroelectric
characteristics. The ferroelectric ceramic material includes an oxide represented by theformula: (100−a−b)BaTiO.aBiO.bMO, where M represents a trivalent metal other than Bi,and a and b satisfy 1≦a≦15, 0≦b≦5, and 5≦a+3≦15 and M is preferably a trivalent metalselected from fifth period transition metals or rare earth metals having an atomicnumber of 59 or higher to 69 or lower.
