PROBLEM TO BE SOLVED: To provide a pressure sensor preventing the disconnection of a lid causing the leakage of a material for pressure detection, and having a high sensitivity to outputs. SOLUTION: At least one pressure introduction hole 26 is provided to extend to the lower surface of a pressure receiving board 29 from the outer surface of a fitting part 21 into which a mating pressure introduction pipe 43 is fitted in such a manner as to enclose a lid 42 containing the pressure receiving board 29, a placement part 38 and an electronic component 40 therein. The material 44 for pressure detection is brought into contact with the pressure receiving board 28 via the pressure introduction hole 26, and the pressure of the material 44 for pressure detection is detected by means of the pressure receiving board 29.
