A soundproof engine-driven operating machine has a small installation area, is easy to assemble and disassemble, and has superior cooling effects. The soundproof engine-driven operating machine comprises an engine, a operating machine main body that is driven by the engine, a base frame that supports the engine and the operating machine main body in a vibration-proof structure, and a case that is fitted to the base frame and accommodates the engine and the operating machine main body. One part of the case includes a first-storey chamber that accommodates the engine and the operating machine main body, first and second heat exchangers, each having a cooling fan and being arranged above the first-storey chamber, the first and second heat exchangers performing heat conversion relating to the operation of the engine by using the cooling fans, arranged separately in a ventilation path, and a second-storey chamber that accommodates a muffler for discharging engine air. The part of the case is comprised from a structural frame that is provided on the base frame. A cover is secured to the base frame, and covers the entire structural frame.
