Provided is a compact casting apparatus capable of producing a high-quality casted product. While the internal pressures of a mold and a hopper are directly reduced by depressurizing means through a pipe and a branch pipe, the mold and the hopper are gradually tilted to fill the mold with a molten metal accommodated in the hopper. After the filling is completed, an open-close gate closes a runner. The molten metal is solidified with only the mold being directly pressured by pressurizing means through the pipe.
