PROBLEM TO BE SOLVED: To obtain a pressure sensor excellent in work efficiency of sealing work at a tip end of a tubular part, capable of reducing the costs necessary for the work. SOLUTION: In a pressure sensor 10, an insertion part 62 of a sealing member 60 is engaged from an upper end of a tubular part 40 until the edge face 66A of a flange part 66 of the member 60 abuts on the upper end face 40A of the tubular part 40. In this state, a ring-like pressure contact part 64 formed on the outer circumference part of the insertion part 62 is pressure-contacted to the inner circumference part of the tubular part 40, thereby the upper end part of the tubular part 40 is sealed. Like this manner, since the upper end part of the tubular part 40 can be sealed only by engaging the member 60, the work efficiency of the sealing work is improved. In a state in which the member 60 is engaged with the tubular part 40, a tubular part inside cavity 68 is formed between the insertion part 62 and the upper end part of a sensor main body 14. Accordingly, even when the main body 14 moves slightly toward an upper side, the main body 14 does not press the insertion part 62 upward and the member 60 does not drop off.
