Abstract
An electric wire insertion hole () arranged in a housing (), an ventilation path of inside space () of which one end is opened to a pressure sensor internal space () and an intersection portion () communicating the both each other are provided. Since the electric wire insertion hole () and the intersection () intersect at right angles, water or dust entering into the electric wire insertion hole () does not enter a lot into the intersection (). Therefore, water or dust hardly enters into the pressure sensor internal space (). There is no need of a waterproof or a dustproof filter or the like to prevent water or dust, hence low cost manufacturing can be achieved.
