。 A mechanical supercharger is arranged in the engine intake passage downstream of the throttle valve, and a bypass passage is branched from the intake passage between the throttle valve and the mechanical supercharger, and the bypass passage is connected to the intake passage downstream of the mechanical supercharger. A bypass control valve is connected to the bypass passage and controlled by an actuator, and the absolute pressure generated in the intake passage between the throttle valve and the mechanical supercharger is transmitted through the pressure transmission passage. In a supercharging pressure control device for an internal combustion engine, which closes the bypass control valve as the absolute pressure increases by guiding it to an actuator, an intake passage upstream of the throttle valve is connected to the pressure transmission passage through a communication passage. A boost pressure control device for an internal combustion engine, wherein a communication control valve is provided in the communication passage and opens when the engine idles up.
