PROBLEM TO BE SOLVED: To improve detection accuracy of a pressure sensor and a temperature sensor, while modularizing the sensors. SOLUTION: The sensor unit comprises: the temperature sensor 40 detecting an intake temperature upstream of a valve element V opening/closing an intake passage B1; the pressure sensor 30 detecting intake pressure downstream of the valve element V; and a casing integrally holding the temperature sensor and the pressure sensor. In the casing, a casing main body 10 and a rubber pipe 60 constitute a pressure guide passage 11a guiding pressure to be detected into the pressure sensor 30, and an intake guide passage 12a guiding intake upstream of the valve element V from around the temperature sensor 40 into the pressure guide passage 11a. Therefore, influence of heat from a throttle body B is suppressed to detect the intake temperature with high accuracy, and back flow of blow-by gas or the like is prevented to stabilize the intake pressure and to stably detect the pressure with high accuracy.
