Sensor Unit
Abstract: A sensor unit (20) is provided inside a casing (52) with an intake pressure sensor (94) and an outside air pressure sensor (96), and the intake pressure sensor (94) and the outside air pressure sensor (96) are disposed between a bottom wall (54) of the casing (52) and a wiring surface (98) of a board (92). Further, a first pressure sensing portion (110) of the intake pressure sensor (94) and a second pressure sensing portion (118) of the outside air pressure sensor (96) are exposed respectively to first and second pressure sensing spaces (112, 120) enclosed by the bottom wall (54), the first pressure sensing space (112) communicates with an intake passage (16) by way of an intake pressure detection passage (74) provided in the casing (52), and the second pressure sensing space (120) communicates with a space portion (128) of the casing (52), which opens to the outside, by way of first and second outside air pressure detection passages (80, 82).
