PURPOSE: A manufacturing method of a concrete lamp post is provided to manufacture various lamp posts with a low price. CONSTITUTION: A manufacturing method of a concrete lamp post is as follows: Metallic upper and lower round molds are formed. A rubber plate is adhered to the outer surface of the metallic upper and lower round molds. Fitting projections and upper and lower rubber molds which have fitting grooves are formed on the outer surface of the metallic upper and lower round molds by pressurizing. The fitting projections of the upper and lower rubber molds and the fitting grooves are coupled, and inserted to the inner surface of a separate mold. A reinforcement material, such as a reinforcing bar, is inserted to the inside of the separate mold, and cement mortar is injected through an injection port. And the concrete lamp post is manufactured using a centrifugal method.
