Because an evaporating apparatus for use in an MOCVD film deposition system has a structure in which a plurality of gas passages brings in a gas from the upper direction, the apparatus has a difficulty to position a jet nozzle, and the apparatus is incapable of accurately controlling the pressure and flow rate of a carrier gas mixed with a raw material solution to be issued into an evaporating unit, and it is thus difficult to highly accurately control the composition of MOCVD films. A plurality of gas passages is arranged on a flat, disk-shaped plate. With this configuration, the accurate positioning of the jet nozzle can be made easier, and the composition of MOCVD films can be controlled highly accurately.
