PROBLEM TO BE SOLVED: To realize a near field light probe that has higher efficiency, that is a higher ratio of the near field light intensity to the input light intensity. SOLUTION: In a near field light probe 1 that is made of a high refraction material and has a projection 3 having a hole smaller than the light wavelength of the light source on the light transmissive substrate 2 provided at the top, an anti-reflection film 7 is provided on the first boundary surface 6 where the light 8 from the light source enters the transmissive substrate 2 through the air layer 5. |
