The present invention relates to an arrowhead, and more particularly, to an arrowhead which enables a plurality of expanding blades to unfold rapidly and reliably, and prevents the expanding blades from folding again inside a target after the expanding blades penetrate the target, and an arrow. According to embodiments of the present invention, since the plurality of expanding blades are adapted to unfold upon entering a target at the same at which the target is hit, the plurality of expanding blades penetrates the target in an unfolded state, and thus it is possible to induce excessive bleeding in game serving as the target, because the expanding blades are prevented from folding again after the expanding blades penetrate the target.
