In a radiation detector, a polycrystalline film is formed by a closed spaced sublimation using a sintered material of at least one of a CdTe and CdZnTe powder. The CdTe or CdZnTe film has a thickness sufficient to catch radiation and a large area corresponding to a size of a supporting base plate, which can be obtained in a short time. Thus, a radiation detector and a radiation image taking device having a large area can be obtained.
