Abstract
A monolithic ceramic capacitor that contains a perovskite compound including Ba and Ti and at least one type of element selected from Gd, Tb, and Dy, and contains elements selected from Y, Si, Mn, Mg, and Zr. The content a of at least one element selected from Gd, Tb, and Dy satisfies 0.2≤a≤0.8, the content b of Y satisfies 0.0≤b≤0.5, the content c of Si satisfies 0.0≤c≤2.5, the content d of Mn satisfies 0.0≤d≤0.25, the content e of Mg satisfies 0.0≤e≤1.2, the content f of Zr satisfies 0.0≤f≤0.5, and the molar ratio m of the content of Ba/(f+the content of Ti) satisfies 0.99≤m≤1.01, where the total content of Ti is 100 parts by mole.
