The present invention provides a method for producing a catalyst for producing propylene, which produces a small amount of paraffin components and aromatic components such as ethylene and propane, and is excellent in propylene yield, propylene / propane ratio, and catalyst life. A propylene production catalyst for producing propylene from one or more selected from the group consisting of methanol, dimethyl ether and olefins having 4 to 8 carbon atoms, wherein the catalyst is a silicon / aluminum atom. It consists of a binderless crystalline aluminosilicate molding with a ratio of 500 to 10000, the crystalline aluminosilicate contains MFI type crystal structure and / or MEL type crystal structure, 3715cm -1 to 3735cm by infrared spectroscopy -1 is a method for producing a catalyst for propylene production in which the peak position of the hydroxyl group of the binderless crystalline aluminosilicate molding is observed within the range of 3725 cm -1 to 3735 cm -1 , which includes a silicon component, A raw material molded body made of a solid component containing an aluminum component and a structure directing agent component is brought into contact with an atmosphere containing saturated water vapor, and silicon A method for producing a propylene production catalyst, characterized in that it comprises a conversion step of converting frequency and the aluminum component in the crystalline aluminosilicate.
