An object is to provide a flat surface inspection apparatus that can prevent sliders from being damaged and detect micro defects. A flat surface inspection apparatus includes: a measured subject; a stage that supports the measured subject; a spindle that rotates the stage; a first part having light sources applying light beam onto the measured subject, a scattered-light-detecting section, a signal processing section that converts the scattered light into information about a first defect, and a first memory section that stores therein the information about the first defect; and a second part having sliders mounted with a contact sensor that detects a second defect smaller than the first defect, a loading/unloading mechanism that flies the slider over the measured subject, a slider control section that controls the loading/unloading mechanism based on the information about the first defects and second defects.
