Research Abstract	We are developing Transition-Edge Sensor (TES) microcalorimeters for gamma rays in the energy range from several hundreds keV upto 1MeV or so. In order to avoid degradation of energy resolution due to position dependence within the thick gamma-ray absorber, we have applied the technique of Position-Sensitive TES (PoST) to the thickness direction of the absorber. We have developed a prototype gamma-ray PoST.
