A near-field optical probe with a resolving power exceeding a diffraction limit of light is provided utilizing near-near-field light. A near-field optical probe is formed by a core and a shading film. The core has a tip surface spotted with inwardly depressed points with respect to the surface. This provides within the tip surface a light intensity distribution in a distributed form instead of a conventional rectangle function. Its Fourier expansion is increased in short-wavelength lattice constant component. Utilizing this component, a near-field optical probe is realized having a resolving power exceeding a diffraction limit of light.
