1. An electronic component comprising:
an element body including outermost, flat surfaces and a depression that is recessed from the outermost, flat surfaces; and
a terminal electrode on the element body, wherein
the terminal electrode includes a first electrode portion in the depression and an integral second electrode portion protruding beyond the outermost, flat surfaces from the depression,
the second electrode portion is thicker than the first electrode portion,
the outermost, flat surfaces include a main face constituting a mounting surface and an end face adjacent to the main face,
the depression includes an end-face depression in the end face and a main-face depression in the main face,
the first electrode portion includes a first end-face electrode part in the end-face depression and a first main-face electrode part in the main-face depression,
the second electrode portion includes a second end-face electrode part protruding beyond the end face from the end-face depression and a second main-face electrode part protruding beyond the main face from the main-face depression,
the element body contains a sintered body of an insulating material,
the terminal electrode contains a sintered body of a conductive material,
the first electrode portion and the second electrode portion are comprised of a same material,
each of the first main-face electrode part and the second main-face electrode part has a flat end edge surface that is (i) parallel to the end face and (ii) is a continuous flat surface between all edges of the flat end edge surface,
the flat end edge surfaces of the first main-face electrode part and the second main-face electrode part abut edge-to-edge to form a combined continuous flat edge surface, and
the first main-face electrode part and the first end-face electrode part have a same thickness.
