A dielectric material includes a barium titanate based base material main ingredient and an accessory ingredient. In a fine sintered structure of the dielectric material, crystal grains in which a content of Ca is less than 2.5 mol % are first crystal grains, crystal grains in which the content of Ca is 4.0 to 12.0 mol % are second crystal grains, and a ratio of an average size of the first crystal grains to an average size of the second crystal grains is in a range of 1.6 to 2.2. |
