<P>PROBLEM TO BE SOLVED: To provide a dielectric porcelain composition which has high volume resistivity while maintaining such characteristics that it has a high dielectric constant ε, a large Q value at a frequency of 1 MHz or higher, and a dielectric constant hardly undergoing change due to temperature change; and a ceramic electronic component prepared by using the dielectric porcelain composition. <P>SOLUTION: The dielectric porcelain composition contains a main component represented by a[(Sr<SB>b</SB>Ca<SB>1-b</SB>)TiO<SB>3</SB>]-(1-a)[Bi<SB>2</SB>O<SB>3</SB>nTiO<SB>2</SB>] and an auxiliary component represented by wMgTiO<SB>3</SB>+xSiO<SB>2</SB>+yMnO<SB>m</SB>+zLnO<SB>k</SB>, wherein each of a, b, and n means a molar ratio, satisfying the expressions: 0.90≤a≤0.95, 0.90≤b≤0.95, and 1.8≤n≤3.0; and each of w, x, y, and z means pts.wt., satisfying 5.0≤w≤10.0, 0.1≤x≤1.0, 0.1≤y≤0.3, and 1.0≤z≤5.0. Each of w, x, and z is based on 100 pts.wt. of the main component; and y means pts.wt. of MnO<SB>m</SB>(in terms of MnCO<SB>3</SB>) and is based on 100 pts.wt. of the main component. Ln is at least one kind of element selected from among La, Ce, Pr, Nd, Sm, Eu, Gd, Dy, Ho, and Er. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
