Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a solid catalyst which gives a cyclic carbonate at a high yield and a high selectivity, which is stable and which is readily separated after reaction, and a method of industrially advantageous, inexpensive and safe continuous distribution type synthesis of the cyclic carbonate by the use of the catalyst. SOLUTION: A catalyst containing an ionic substance containing a Group 15 element and an inorganic solid substance is used as the catalyst. The ionic substance containing a Group 15 element is at least one substance selected from organic phosphonium salts, organic ammonium salts, organic arsonium salts and organic antimonium salts.
