1. A laminated electronic component comprising:
a body including a magnetic layer containing magnetic particles;
a coil provided within the body; and
outer electrodes provided on a bottom surface of the body and each electrically connected to any one of end portions of the coil, wherein
in a cross-section perpendicular to the bottom surface of the body, each outer electrode has a first outer surface facing outward from the bottom surface of the body and a second outer surface facing into the body, and a side surface of each outer electrode has a recess-shaped wedge portion, and a part of the body enters the wedge portion,
the side surface of each outer electrode having the recess-shaped wedge portion has a first extension portion at the bottom surface of the body, and a second extension portion nearest to the first extension portion and deeper into the body, which configure the wedge portion, and respective lengths of the first and second extension portions are about the same,
the first extension portion has a first outer surface facing outward from the body that is part of the first outer surface of the outer electrode, and the second extension portion has a second outer surface facing into the body that is part of the second outer surface of the electrode, and
at the bottom surface of the body, at least a part of a surface of each outer electrode is located outward of the bottom surface of the body.
