1. A coil component comprising:
a core body formed of a magnetic material, the core body having:
a mounting surface;
an upper surface, the upper surface and the mounting surface being outwardly opposite to each other; and
a first side surface joining the mounting surface and the upper surface;
a coil having:
an embedded part embedded in the core body; and
a first protruding part protruding from the core body; and
a first metal terminal electrically connected to the first protruding part of the coil, the first metal terminal having:
a first plate arranged along the first side surface of the core body;
a second plate continuously extending from an upper end of the first plate and arranged along the upper surface of the core body; and
a third plate continuously extending from a lower end of the first plate and arranged along the mounting surface of the core body,
wherein a leading edge of the second plate is recessed toward the upper end of the first plate to form a first arc-shaped part,
the upper surface of the core body has a first recess in which the second plate is arranged, and
the first recess has a second arc-shaped part facing the first arc-shaped part, and the second arc-shaped part extends along a contour of the first arc-shaped part.
