A dielectric ceramic layer (3) is configured to contain, in the form of elements, Ba, Sr, La, Ti, Zr, M (at least one element selected from among Mg, Al, Mn and V) and Si, while containing, in the form of a compound, a perovskite compound that is configured to contain Ba, Sr, La, Ti and Zr. In this connection, if the amount of each element is expressed in parts by mole and the total of the amount of Ti and the amount of Zr is taken as 100, the amount (a) of Sr satisfies 5.0 ≤ a ≤ 20.0, the amount (b) of La satisfies 0.5 ≤ b ≤ 1.9, the amount (c) of Zr satisfies 30 ≤ c ≤ 40, the amount (d) of M satisfies 0.5 ≤ d ≤ 3.0, the amount (e) of Si satisfies 0.5 ≤ e ≤ 3.0, and the ratio (m) of the total of the amount of Ba, the amount of Sr and the amount of Re relative to the total of the amount of Ti and the amount of Zr satisfies 0.990 ≤ m ≤ 1.050. |
