PROBLEM TO BE SOLVED: To provide an optical element and an optical detection device capable of achieving a desired optical characteristics with satisfactory controllability.SOLUTION: The optical element has a first plane and a second plane opposite the first plane including a first area. The first refraction index in the first area is asymmetry with respect to a first axis parallel to a first thickness direction which passes a first position where the first refraction index is the maximum or minimum in the first area extending from the first plane to the second plane in the first area. |
