Hot electron photoconductive detectors for the submillimeter to millimeter wavelength region have been constructed using high purity n-type indium antimonide with N_D-N_A〜10^<14> and their characteristics such as spectral responsivity, responsivity dependence on the chopping frequency, noise and noise equivalent power (NEP), etc. have been investigated. The noise decreases according to 1/f^y(y≈1.4) with increasing chopping frequency f. NEP's of 3.8×10^<-13> W/Hz^<1/2> at 4.2 K and 3.1×10^<-13> W/Hz^<1/2> at 1.7 K are obtained at an optimum wavelength and at a chopping frequency of 1350 Hz. These values are inferior to those of an ideal photoconductor by a factor of about 4.
