Abstract
A pipe having a through-hole of smaller diameter than a pressure port is disposed in the pressure port. Therefore, a volume of the pressure port can be reduced by the thickness of the pipe, thereby improving response of a pressure sensor. Furthermore, there is no need for the pressure port having smaller diameter to be provided by drill processing, so that a volume in the pressure port can be easily adjusted. Accordingly, the volume in the pressure port can be reduced with a simple structure to improve response of the pressure sensor.
