PROBLEM TO BE SOLVED: To provide a fuel control device for a multi-cylinder internal combustion engine capable of equalizing air-fuel ratios between cylinders even though operating conditions are changed. SOLUTION: Gaseous fuel supplied to a mixer 3 through a fuel supply pipe 4 fills an annular fuel chamber 14, is supplied from the pair of fuel supply openings 13 of an annular member 11 into an intake air passage 10, and sucked into two or more air cylinders of an gas engine as a fuel/air mixture. The operating conditions of the gas engine are grasped based on the engine speed N of the gas engine detected by an engine speed sensor and intake air pressure P in an intake pipe 2 detected by a pressure sensor, the annular member 11 is rotated by a motor 5 so that the air-fuel ratios between two or more air cylinders of the gas engine are equalized according to the operating conditions of the gas engine, and the positions of the pair of fuel supply openings 13 to the intake air passage 10 are moved and controlled.
