PROBLEM TO BE SOLVED: To provide a method for manufacturing a proximity field light generating element which allows the formation of a microopening in nearly an exact position at the exit surface of the element and allows the easy alignment of the microopening and an imagery point even if the eccentricity in inclination or the eccentricity in parallel arises in the element in the working, and to provide a method for regurating this element. SOLUTION: This proximity field light generating element (solid immersion mirror) 10 forms an image in the central part of a second surface 12 by reflecting the laser beam L made incident on the peripheral part of a first surface 11 of a plane shape at a second surface 12 in the form of a paraboloid of revolution and further reflecting the same in the central part of the first surface 11. The microopening 14a is formed at a reflection film 14 deposited on the second surface 12 in the highest position with respect to the first surface 11. The microopening 14a is formed by irradiating the reflection film 14 consisting of metallic material with, for example, electrons or ions to eliminate the reflection film 14 of the highest position. |
