Abstract
A pressure sensor having a structure in which compressible fluid is prevented from stagnating in the vicinity of a pressure-receiving surface of the pressure sensor in the interior of a pressure introducing portion is provided. In a pressure sensor including a sensor body arranged in a pressure introduction flow channel branched in a T-shape upward from a primary fluid flow channel in which fluid to be subjected to pressure measurement flows, the pressure introduction flow channel includes an inclined surface extending in a direction to increase an opening area on the side of an inlet port of the fluid on a wall surface on the downstream side in terms of the direction of flow of the fluid.
