Abstract
The radiation image conversion panel includes a phosphor layer formed by a vapor-phase deposition and solely formed of columnar crystals, a matrix layer formed under the phosphor layer, is substantially free of an activator of a phosphor, and has a columnar crystal region and an underlying non-columnar crystal region and a substrate which supports the matrix layer and the phosphor layer formed on the matrix layer. The process for producing the radiation image conversion panel forms on the substrate the matrix layer and forms the phosphor layer by the vapor-phase deposition. The formation of the phosphor layer is started after a crystal structure of an upper region of the matrix layer has changed from a non-columnar to a columnar.
