PROBLEM TO BE SOLVED: To provide a seal structure of a pressure sensor capable of securing the sealing property in a joint between a detection pipe and an introduction pipe while omitting hose clip. SOLUTION: A projecting part 15 for increasing the sliding contact area with first and second hoses 12b and 13b is formed on the outer peripheral surfaces of first and second pressure introduction ports 12a and 13a. A projecting part 16 for increasing the sliding contact area with the outer peripheral surfaces of the first and second hoses 12b and 13b is formed on the inner peripheral surfaces of the first and second pressure introduction ports 12a and 13a. Here, the projecting part 15 is formed over three strings in cross-sectional triangle shapes in a part of the outer peripheral surfaces of the base ends of both ports 12a and 13a. The projecting part 16 is formed so as to mesh with the projecting part 15 in a part of the inner peripheral surfaces of the tips of both hoses 12b and 13b, and is formed over three strings in cross-sectional triangle shapes in a part of the inner peripheral surfaces of the tips of both hoses 12b and 13b.
