PROBLEM TO BE SOLVED: To provide an air pressure detection device which improves sealing performance of an opening part.SOLUTION: In an air pressure detection device 30, a pressure sensor element 33 is stored in a case which assumes a box shape. The pressure sensor element 33 is stored in such a state that a pressure receiving part 37 and an outer part of the case are communicated via an opening part 44. The opening part 44 is provided on a bottom plate 43 of the case. On the bottom plate 43, a first erection part 45 which surrounds a pressure introduction port 36 of the pressure sensor element 33 and a second erection part 51 which is erected along an outer surface 33b of the pressure sensor element 33 are provided. Seal material 61 made by curing liquid gasket is disposed between the bottom plate 43 of the case and a joint surface 33a of the pressure sensor element 33, between an outer circumferential surface 45a of the first erection part 45 and an inner circumferential surface 36a of the pressure introduction port 36 and between an inside surface 51a of the second erection part 51 and the outer surface 33b of the pressure sensor element 33. |
