    Abstract: A conductive resin layer includes a first region positioned on the end surface, a second region positioned on the side surface, and a third region positioned on a ridge portion between the end surface and the side surface. In a case where a maximum thickness of the first region is T1 (μm) and a maximum thickness of the second region is T2 (μm), the maximum thickness T1 and the maximum thickness T2 satisfy a relation of T2/T1≥0.11. In a cross-section along a thickness direction of the first region, a total area of voids in the first region is in a range of 5.0 to 36.0% of an area of the first region. In a cross-section along a thickness direction of the second region, a total area of voids in the second region is in the range of 5.0 to 36.0% of an area of the second region.

    Abstract: Each of a plurality of internal electrodes is electrically connected to a corresponding external electrode of a plurality of external electrodes. A plurality of auxiliary internal electrodes are disposed in the same layer as the plurality of internal electrodes to be located between each of a pair of side surfaces and the plurality of internal electrodes. Each of the plurality of external electrodes includes a pair of side surface electrode portions disposed on the pair of side surfaces and including a conductive resin layer. Each of the plurality of auxiliary internal electrodes is electrically connected to the external electrode to which the internal electrode located in the same layer is not electrically connected, and is located between the conductive resin layer to which the internal electrode located in the same layer is not electrically connected and the internal electrode located in the same layer.

    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 third direction is shorter than that of the element body in the first direction and 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. Each of the first external electrodes includes a first conductor part disposed on one main surface and a second conductor part disposed on the end surface and coupled to the first conductor part. The porosity of the first conductor part is smaller than that of the second conductor part.

    Abstract: An electronic component includes an element body including a plurality of side surfaces adjacent to each other, and an external electrode disposed on the plurality of side surfaces. The external electrode includes a conductive resin layer in which a plurality of gaps exists and a plating layer disposed on the conductive resin layer. A clearance communicating with the plurality of gaps exists between an end edge of the plating layer and the element body. The conductive resin layer includes a first portion located on one side surface of the plurality of side surfaces and a second portion located on another side surface of the plurality of side surfaces. An existence ratio of the gaps in the first portion is greater than an existence ratio of the gaps in the second portion.
