Provided are a high resistance CdTe-based compound single crystal with miniaturized Te precipitates and a method for producing the same. According to one embodiment of the present invention, a CdTe based compound single crystal is provided including a precipitate having a particle size of less than 0.1 μm obtained from an analysis by a light scattering tomography method. In the CdTe based compound single crystal, resistivity may be 1×107 Ωcm or more. In addition, in the CdTe based compound single crystal, a precipitate having a particle size of 0.1 μm or more obtained from the analysis by the light scattering tomography method is not detected. In the CdTe based compound single crystal, the precipitate may be a Te precipitate.
