A surface inspection apparatus includes an illumination means for illuminating a pattern formed through a predetermined pattern forming process containing a process of exposure of a resist layer formed on a substrate having a periodicity with a linearly polarized light, a setting means for setting a direction of the substrate such that a plane of vibration of the linear polarization and a direction of repetition of the pattern are obliquely to each other, an extraction means for extracting a polarization component having a plane of vibration perpendicular to that of the linear polarization out of specularly reflected light from the pattern, and an image forming means for forming an image of the surface of the substrate based on the extracted light. A pattern forming condition in the pattern forming process is specified based on the light intensity of the image of the surface of the substrate formed by the image forming means.
