A mixer for a multicylinder gas engine is provided in which a plurality of intake passages extend to a plurality of cylinders. A plurality of gaseous fuel nozzles, each having a nozzle orifice opening in a venturi part of the corresponding intak e passage, are provided in a mixer main body. The plurality of gaseous fuel nozzles are connected to a gaseous fuel supply device, wherein a common surge tank housi ng the plurality of gaseous fuel nozzles and having a fuel intake pipe opening therein is provided on the mixer main body. The fuel intake pipe extends to the gaseous fuel supply device. Intake pressure pulsations that have passed through the gaseo us fuel nozzles are attenuated within the surge tank, thereby achieving uniform distribution of a gaseous mixture to each cylinder, minimizes the number of parts, and prevents fluctuations in the fuel concentration of the gaseous mixture.< /SDOAB>
