Abstract: PROBLEM TO BE SOLVED: To produce a single crystal SiC in a good productivity, which can be used for producing a semiconductor device having good characteristics, by surely and uniformly dispersing impurities without lowering crystallinity of a high quality single crystal almost free from micropipe defects or the like. SOLUTION: An SiC single crystal base material 1 and a polycrystal plate 3 produced in a plate form by a thermal CVD method are laminated in the adhesion state while interposing an organic or inorganic intermediate layer 4 containing SiO as a fundamental component between the facing surfaces of the base material and the polycrystal plate to obtain a composite body M. Then, the composite body M is heat-treated in a crucible 7 so that a single crystal is grown by a solid growth comprising subjecting polycrystal bodies of the polycrystal plate 3 to crystal modification to the same orientation as that of a single crystal of the SiC single crystal base material.  At this time, an impurity element such as boron, aluminum or nitrogen or one of the compounds of these elements is added to the peripheral parts of the composite body M by thermal diffusion so that the impurity element or the compound is introduced into the solid-growing single crystal.
