Abstract
Provided is a sensor head that can increase the flexibility of installation. The sensor head is a sensor head of a sensor for measuring displacement of a measurement object. The sensor head includes: a diffractive lens generating chromatic aberration along an optical axis direction on an incident light, a case part housing at least the diffractive lens inside, and fixing parts and used for fixing to a fixing object. The case part includes a cylindrical part having a cylindrical outer shape, and the outer shapes of the fixing parts and are within the outer shape of the cylindrical part when viewed in a central axis direction of the cylindrical part.
