We developed resistive electrode position sensitive CdTe detectors and a prototype PET camera which included them in order to achieve a high sensitive semiconductor PET camera. It was determine that a high resistive electrode on a CdTe detector could be made by changing a thickness of an electrode metal. 1-dimensional position sensitive detectors were made by this method, and a good position resolution of 1.2 mm FWHM was confirmed. The prototype camera was built with these detectors. Reconstructed images of 22Na were obtained with the prototype. Resolutions are 0.8 mm (FWHM) in transaxial, and 1.6 mm (FWHM) in axial.
