<P>PROBLEM TO BE SOLVED: To provide a dielectric porcelain composition which enhances a dielectric constant and a Q value, downsizes a dielectric filter and a resonator, and reduces a dielectric loss, and can be sintered at a temperature lower than a melting point of silver, copper or the like. <P>SOLUTION: 25-35 pts.wt. of a Li glass is added to 100 pts.wt. of a composition represented by a general formula: xMgTiO<SB>3</SB>*yMg<SB>2</SB>TiO<SB>4</SB>*zCaTiO<SB>3</SB>, where x, y, and z are respectively in the range of 69.3≤x≤84.0, 14.1≤y≤30.0, and 0.8≤z≤6.1 by mol%. Thus, the dielectric constant and the Q value are improved while a sintering temperature can be lowered to a temperature lower than a melting point of a metal composed of a conductor pattern. <P>COPYRIGHT: (C)2008,JPO&INPIT |
