The invention provides a controller and control method for a supercharger-equipped internal combustion engine capable of assisting the insufficient part of supercharging pressure supercharged by the turbocharger, with a good responsiveness by the electric compressor, using simple calculation, even though using a plurality of superchargers. The controller (100) for supercharger-equipped internal combustion engine comprises an electric compressor rotational speed control unit (151) that calculates a value obtained by subtracting, from the target supercharging pressure (P2t), a pressure difference obtained by subtracting the real intermediate supercharging pressure (P12r) from the real supercharging pressure (P2r), as a target intermediate supercharging pressure, and calculates a target rotational speed (Necpt) of the electric compressor, based on a ratio of the target intermediate supercharging pressure and the real atmospheric pressure (P1r) and the real intake air flow rate (Qar) so asto control an electric motor (43).
