1. An electronic component comprising:
an element body in which a plurality of insulator layers are stacked, the element body having a rectangular parallelepiped shape with a pair of end surfaces facing each other and a pair of principal surfaces facing each other and extending to connect the pair of end surfaces to each other;
an inner conductor in the element body; and
an outer electrode that (i) is on an outer surface of the element body, the outer surface being one of the pair of end surfaces of the element body, (ii) is electrically connected to the inner conductor and (iii) includes:
a first electrode layer including a first portion that is directly on the outer surface and a second portion that is directly on the pair of principal surfaces of the element body, the second portion being continuous from the first portion;
a second electrode layer that is on an opposite side of the first electrode layer from the element body;
a plurality of spaced connecting portions that (i) is between the first electrode layer and the second electrode layer and (ii) electrically connects the first electrode layer and the second electrode layer; and
a plurality of spaced insulating portions that (i) is between the first electrode layer and the second electrode layer and (ii) electrically insulates the first electrode layer and the second electrode layer from each other, wherein:
the insulating portions are filled with glass;
each of the plurality of spaced connecting portions is separated, along the outer surface of the element body, from adjacent ones of the plurality of spaced connecting portions by one of the plurality of spaced insulating portions such that the first electrode layer and the second electrode layer are partially electrically connected to each other via the plurality of spaced connecting portions but not by the plurality of spaced insulating portions;
the second electrode layer covers an entirety of the first portion of the first electrode layer and an entirety of the second portion of the first electrode layer;
the second electrode layer includes: (i) a first cover portion formed on the outer surface and covering the entirety of the first portion of the first electrode layer, and (ii) a second cover portion formed on the pair of principal surfaces and covering the entirety of the second portion of the first electrode layer, and
the plurality of spaced connecting portions are disposed only on the outer surface between the first cover portion of the second electrode layer and the first portion of the first electrode layer, without being disposed on the pair of principal surfaces between the second cover portion of the second electrode layer and the second portion of the first electrode layer.
