To provide a method for producing an organic carbonate, by which the organic carbonate can be produced in good production efficiency without using a large amount of a harmful metal compound and a dehydrating agent.

Provided is the method for producing an organic carbonate represented by general formula (2), characterized by reacting a silicon alkoxide represented by general formula (1) with carbon dioxide in the presence of a metal alkoxide having Lewis acidity. Therein, R1, R2 are each H, an alkyl group, an aralkyl group, an aryl group, or a cycloalkyl group; R3, R4 are each an organic group.
