PURPOSE: A thickness measuring apparatus is provided to secure the degree of precision by stably combining a sensor unit. CONSTITUTION: A thickness measuring apparatus (100) comprises a sensor unit, a lower case (120), a side support unit, and an upper case (140). The sensor unit measures the thickness of a measured object by being equipped with a light emitting unit which sends light onto the measured object, and a light receiving unit which receives the light reflected from the measured object. The lower case forms an opening so that a ray of light passes through between the light emitting unit and the light receiving unit, and fixes the sensor unit to be detachable. The side support unit has one end which is detachably connected to the lower case, and the other end which fixes and supports the sensor unit to be detachable. The upper case wraps around the sensor unit and the side support unit, and detachably connected to the lower case.
