Capacitor with barium titanate dielectric layers
A capacitor includes a stack and an external electrode located on a surface of the stack. The stack includes a plurality of dielectric layers and a plurality of internal electrode layers alternately stacked on one another. Crystal grains include first crystal grains having a small grain size and second crystal grains having a larger grain size. The first crystal grains satisfy 0.13 μm≤d1<0.30 μm, where d1 is the grain size of the first crystal grains. The second crystal grains satisfy 0.30 μm≤d2<0.50 μm, where d2 is the grain size of the second crystal grains. The second crystal grains have a higher additive element content than the first crystal grains.
