Abstract: A multilayer ceramic capacitor includes a multilayer body including dielectric layers and first and second inner electrode layers. The first inner electrode layers include first counter electrode portions facing the second inner electrode layers and first extended portions extending from the first counter electrode portions to a first end surface. The second inner electrode layers include a second counter electrode portions opposing the first inner electrode layers and second extended portions extending from the second counter electrode portions to a first side surface. The first extended portions include a first connection portion connected to straddle at least two or more of the first extended portions in the lamination direction, between the first extended portions, and the second extended portions include a second connection portion connected to straddle at least two or more of the second extended portions in the lamination direction, between the second extended portions.

Abstract: In a multilayer ceramic capacitor, a dimension of each of first and second extension portions in a width direction is less than a dimension of a first counter electrode portion in the width direction, and a dimension from a side of each of the first and second extension portions near a first lateral surface to the first lateral surface in the width direction and a dimension from a side of each of the first and second extension portions near a second lateral surface to the second lateral surface in the width direction are each greater than the dimension of each of the first and second extension portions in the width direction.

Abstract: A multilayer ceramic capacitor includes a laminate including dielectric layers and internal electrodes that are laminated, and external electrodes disposed on side surfaces of the laminate to be connected to corresponding internal electrodes. A dimension L of the multilayer ceramic capacitor in its lengthwise direction and a dimension W in its width direction satisfy: about 0.85≤W/L≤about 1, and L≤about 750 μm, and a dimension T in its lamination direction satisfies: about 70 μm≤T≤about 110 μm. The laminate has a dimension t in the lamination direction, and a region in which the internal electrodes are laminated has a dimension t′ in the lamination direction, and a ratio of the dimensions satisfies: t′/t≥about 0.55.
