Abstract: PROBLEM TO BE SOLVED: To provide a clathrate compound semiconductor capable of operating stably even at a high temperature and under a high pressure and having a wide forbidden band, and also to provide a method capable of easily producing the clathrate compound semiconductor. SOLUTION: Group 4B atoms in the periodic table each are employed as a clathrate lattice which includes a specified atom having a smaller electronegativity than that of the clathrate lattice atom. Further, a part of the clathrate lattice atoms is replaced with specified atoms having more or less electronic number than that of the clathrate lattice, and hence a P type or a N type semiconductor is obtained. Doping or substituted elements-containing compounds that have one or more atoms selected from group 4B atoms in the periodic table are melted or pulverized in an inert atmosphere and are maintained for 10 hours or more at 500 deg.C or higher, and thereafter, are cooled. Subsequently, the cooled compounds are washed to remove excessive raw materials, and are thereafter hot press-molded.  Intercalant graphite intercalation compounds can be employed as the above compounds that have one or more atoms of group 4B.
