Zusammenfassung:	PURPOSE:To obtain the titled compound readily and in high selectivity, by using a novel crystalline aluminosilicate zeolite containing an alkaline earth metal having stable activity as a catalyst and bringing methanol into contact with the catalyst under a specific reaction condition in a gas phase. CONSTITUTION:Methanol and/or dimethyl ether in a gas phase is brought into contact with an crystalline aluminosilicate zeolite catalyst containing an alkaline earth metal which has 5-6Angstrom pore diameter, a composition shown by the formula (M is alkali metal and/or H; M' is alkaline earth metal, preferably Ca; a=0-1.5; b=0.2-40; with the proviso that a+b>1; c=12-3,000: n:0-40), X-ray diffraction figure shown by the table and is produced by previously adding an alkaline earth metallic salt to a crystal producing raw material in the production of the crystal, at 0.1-20hr weight time space velocity at 300-600 deg.C under 0.1-100atm. total pressure to give the aimed compound, especially ethylene or propylene.
