A dielectric porcelain composition includes MgTiO3 and Mg2SiO4 and satisfies a+b=1 and 0<b<1, wherein a denotes a molar ratio of MgTiO3 and b denotes a molar ratio of Mg2SiO4. It can include MgTiO3 and CaTiO3 and satisfy a+c=1 and 0<c<=0.15, wherein a has the same meaning as shown above and c denotes a molar ratio of CaTiO3. It can also include MgTiO3, Mg2SiO4 and CaTiO3 and satisfy a+b+c=1, 0<b<1 and 0<c<=0.15, wherein a, b and c have the same meanings as shown above. These compositions can be manufactured, with the content of Mg2SiO4, the content of CatiO3 and the contents of Mg2SiO4 and CaTiO3 adjusted, respectively. These compositions can be used as dielectric materials to manufacture dielectric resonators.
