Claim 1:
2. Ceramic material powder comprising:
a main phase having a perovskite structure expressed by a general formula ABO3, said perovskite structure being selected from the group consisting of BaTiO3, CaZrO3, CaTiO3, SrTiO3, and Ba1-x-yCaxSryTi1-zZr2O3 (0≤x≤1, 0≤y≤1, z=0);
an element acting as a donor, in a B site of the perovskite structure; and
a rare earth element solid-solved in an A site and the B site of the perovskite structure,
wherein (an amount of the rare earth element substitutionally solid-solved in the A site)/(an amount of the rare earth element substitutionally solid-solved in the B site) is 0.75 or more and 1.25 or less,
wherein the amount of the element that acts as the donor and is substitutionally solid-solved in the B site is 0.05 at% or more and 0.3 at% or less when an amount of a main component element of the B site is 100 at%.
