Abstract
A circuit board has a hollow space partitioned with a detection film on the front side exposed in a passage. The circuit board is accommodated in a recess of a support member and opposed to a bottom surface of the recess on the rear side. The bottom surface of the recess has a groove on one side in both the X-axis and Y-axis directions relative to the detection film. The groove inclines airflow in the groove relative to both the X-axis and Y-axis directions to guide the airflow toward the rear side of the detection film.
