Abstract
A dielectric composition includes a main phase and a Ca—Zr—Si—O segregation phase. The main phase includes a main component expressed by ABO3. “A” includes at least one selected from calcium and strontium. “B” includes at least one selected from zirconium, titanium, hafnium, and manganese. The Ca—Zr—Si—O segregation phase includes at least calcium, zirconium, and silicon. The Ca—Zr—Si—O segregation phase includes 0.12-0.50 parts by mol of zirconium, provided that a total of calcium, strontium, silicon, and zirconium included in the Ca—Zr—Si—O segregation phase is 1 part by mol.
