Provided an optical element and LED lighting device capable of suppressing a decrease in luminance. An optical element according to the present embodiment, the incident surface facing the light source, and a side surface intersecting the incident surface, a shape which is convex toward the opposite vital said side surface and intersects the incident surface on the incident surface a recess surface having, an optical element comprising, the recess surface includes a first surface central axis passes connecting the center portion of the recess surface and the center portion of the incident surface, the first surface and connected to the second surface, anda third surface connected to the side surface is connected to the second surface, along the central axis, to the incident surface from the recess surface the distance L, and the distance from the center of the incident surface to the peripheral edge of the incident surface and r, when the refractive index of the optical element as n, a condition is satisfied.
