Provided is an optical displacement meter capable of accurately detecting a displacement of an object. A light-projecting part selectively irradiates a workpiece with first and second light whose polarization directions are different from each other. Reflected light from the workpiece is incident on a light-receiving element through a light-receiving lens. A waveform creating part creates first and second waveform data showing light-receiving amount distributions of the first and second light obtained by the light-receiving element. A waveform processing part calculates a ratio between mutually corresponding peaks in the first and second waveform data, and selects one peak from each of the first and second waveform data based on the calculated ratios, to detect a position of the peak.
