Abstract: An element body of a rectangular parallelepiped shape has a length in a height direction larger than a length in a width direction and has a length in a longitudinal direction larger than the length in the height direction. A terminal electrode is disposed at an end of the element body in the width direction and extends in the longitudinal direction. The element body includes a pair of principle surfaces opposing each other in the height direction, a pair of end surfaces opposing each other in the longitudinal direction, and a pair of side surfaces opposing each other in the width direction. The terminal electrode includes a conductor disposed on the side surface. The conductor includes a protrusion having a length in the longitudinal direction larger than a length in the height direction.

Abstract: An element body includes first and second end surfaces opposing each other in a first direction, first and second side surfaces opposing each other in a second direction, and first and second principal surfaces opposing each other in a third direction. The length of the element body in the second direction is shorter than that of the element body in the first direction, and the length of the element body in the third direction is shorter than that of the element body in the second direction. A pair of first external electrodes is disposed at both ends of the element body in the first direction. A second external electrode is disposed on the element body and positioned between the pair of first external electrodes. The second external electrode includes a first conductor part disposed on the first side surface. A depression is formed in the first conductor part.

Abstract: An element body includes a pair of principal surfaces, a pair of side surfaces, and another pair of side surfaces. Each of a pair of terminal electrodes includes a first electrode portion disposed on the principal surface and a second electrode portion disposed on the side surface. In the element body, a length in a direction in which the pair of principal surfaces oppose each other is smaller than a length in a direction in which the pair of side surfaces oppose each other and smaller than a length in a direction in which the other pair of side surfaces oppose each other. An arithmetic mean deviation of the surface of the first electrode portion is from 0.20 to 0.26 μm. An arithmetic mean deviation of the surface of the second electrode portion is from 0.27 to 0.38 μm.
