PURPOSE: To obtain the subject material having dielectric anisotropy by constructing a mixture of a raw material containing barium, titanium and a rear earth element with a fusing agent. CONSTITUTION: A raw material mixture is obtained from a barium-containing material, a titanium-containing material and a rear earth element-containing material in such a manner that satisfies the formula, xBaO-yTiO2 -zR2 O3 (R is a rear earth element; 0.1<=x<=0.2; 0.6<=y<=0.8; 0.1<=x<=0.2; x+y+z=1). The raw material mixture is compounded with a fusing agent in an amount of 0.2-2 times the total weight of barium, titanium and the rear earth element in terms of oxides to obtain a mixture. This mixture is baked at 900-1500 deg.C to obtain the objective plate-shaped particles. The particles have D/A of <=0.7 (D is the thickness of a plate; A is the square root of the area of a plate). |
