In a gaseous fuel supply device for a supercharged engine that supplies gaseous fuel from the vaporizer and supercharging pressure to a secondary diaphragm chamber of the vaporizer, the secondary chamber of the vaporizer and the intake passage are connected to each other. An on-off valve that is closed during deceleration is connected to the fuel passage between the two, and a check valve that allows flow from the intake passage side toward the secondary chamber is connected in parallel with the on-off valve. A gaseous fuel supply device for a supercharged engine, characterized by:
