1. A coil component comprising:

  • a coil element;

    a body accommodating the coil element therein, having a square pole shape and including;

    a first side surface;

    a second side surface opposite to the first side surface;

    a third side surface orthogonal to the first side surface;

    a fourth side surface opposite to the third side surface; and

    a bottom surface orthogonal to the first to fourth side surfaces,a first terminal formed by bending a plate member from the first side surface toward the bottom surface, the first terminal including;

    a first end coupled with the coil element and fixed to the first side surface of the body; and

    a second end disposed on the bottom surface of the body and including a pair of corner parts located in both side portions of the second end of the first terminal; and

    a second terminal formed by bending a plate member from the second side surface toward the bottom surface, the second terminal including;

    a first end coupled with the coil element and fixed to the second side surface of the body; and

    a second end disposed on the bottom surface of the body and including a pair of corner parts located in both side portions of the second end of the second terminal,wherein the bottom surface of the body is provided with first to fourth recesses recessed from the bottom surface of the body, the first and third recesses penetrating to the third side surface, the second and fourth recesses penetrating to the fourth side surface,the pair of the corner parts of the first terminal are bent along inner walls of the first and second recesses, respectively, so as to be locked on the bottom surface of the body,the pair of the corner parts of the second terminal are bent along inner walls of the third and fourth recesses, respectively, so as to be locked on the bottom surface of the body,the first to fourth recesses are located so as not to overlap with the coil element, viewed from the bottom surface of the body,the first recess is provided apart from a corner portion of the body where the bottom surface, the first side surface and the third side surface intersect with each other,the second recess is provided apart from a corner portion of the body where the bottom surface, the first side surface and the fourth side surface intersect with each other,the third recess is provided apart from a corner portion of the body where the bottom surface, the second side surface and the third side surface intersect with each other, andthe fourth recess is provided apart from a corner portion of the body where the bottom surface, the second side surface and the fourth side surface intersect with each other.
