We developed a precise position detector for neutrons based on CCD in order to investigate quantum effects of terrestrial gravity. To convert neutrons to charged particles^10B is attached to the CCD surface by a vacuum deposition. To test the performance of the detector we exposed the detector to cold neutrons from JAEA rector at Tokai-mura and ultracold neutrons from a reactor at Institute Laue-Langevin(ILL) France. Successful results were obtained for detection efficiency and position resolution to investigate the quantum effects. Although we could not clearly observe quantum effects of gravity, we searched for and set limits to new short-range forces.
