The optical lens pertaining to the present invention comprises two first optical member arrays in which a plurality of columnar optical members that act on the light incident from light emitting components are arrayed in a state of α° inclination, and a second optical member that is columnar in shape and made of a transparent material, and inside of which the two first optical member arrays are embedded in the columnar axial direction thereof, wherein the material of which the columnar optical members are made has a refractive index that is higher than that of the transparent material of the second optical member. Because the first optical member arrays are integrally embedded in the second optical member, they can be disposed all at once in their proper locations. Also, since the bumpy portions resulting from the curved surfaces of the columnar optical members are not exposed on the outside, no dust accumulates in these portions, which results in an optical lens with superior light emission performance. Furthermore, since the columnar optical members are inclined by α°, the incident light is emitted such that the light has been rotated by 2α° with the optical axis being the center axis.
