<p>An optical probe for a proximity field having a fine aperture for generating and/or scattering a proximity field and capable of being formed into arrays for increasing the intensity of the generated and/or scatted proximity field and being suitable for use as an optical memory head, wherein a flat plate lens having a fine lens is disposed on a plane substrate through which an inverted cone-shaped hole is formed with its top as the above aperture and a light source for emitting a ray of light incident on the flat plate lens is disposed above the lens. Since the focus of the lens is positioned at the fine aperture, a ray of light from the light source is efficiently condensed to the fine aperture. The above structure uses a silicon process to permit array-based production and mass-production of the optical probe, providing an applicability to an optical memory head.</p>
