A fan frame structure with integrated sintered oil-impregnated bearing through insert molding and a method of manufacturing the same are provided. The fan frame includes a sintered oil-impregnated bearing and a fan frame. The bearing has a first and a second end face and an axially extended through hole communicating with the first and second end faces. The fan frame has a base and a bearing cup upward projected from the base to define an axial hollow space therein. The hollow space has a first and a second stop portion, and the bearing is received in the hollow space with the first and second end faces abutted on the first and second stop portions, respectively. With the sintered oil-impregnated bearing integrated with the fan frame through insert molding, increased concentricity between the bearing and the fan frame and reduced manufacturing cost of the fan frame structure can be ensured.
