<P>PROBLEM TO BE SOLVED: To provide dielectric porcelain in which specific dielectric constant and the temperature coefficient of resonance frequency are controllable. <P>SOLUTION: The dielectric porcelain is obtained by consisting essentially of Zr<SB>x</SB>Sn<SB>y</SB>Ti<SB>z</SB>O<SB>4</SB>(x+y+z=2, 0.55<x<1.00, 0.85<z<1.15) and adding respectively ≤1 wt.% (excluding 0) one or more kinds selected from NiO, La<SB>2</SB>O<SB>3</SB>and Ta<SB>2</SB>O<SB>5</SB>where NiO is essential and contains a crystal phase composed of a rutile type crystal structure. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
