<p>PROBLEM TO BE SOLVED: To provide a pressure sensor including a plurality of pressure introduction holes and appropriately introducing a measurement medium into a pressure detection chamber.SOLUTION: First and second pressure introduction holes 32, 33 communicating with a pressure detection chamber 80 including a pressure detection element 20, have opening ends opposite the pressure detection chamber 80 which are oriented in different directions from each other. This configuration prevents the other opening end of the first and second pressure introduction holes 32, 33 from being brought into a water environment even if one opening end of the first and second pressure introduction holes 32, 33 is under the water environment, thus suppressing a measurement medium not being introduced into the pressure detection chamber 80.</p> |
