Provided is a pressure sensor which and accurately detect pressure although sealing resin expands due to heat or shrinks when the sealing resin is chilled because detachment due to thermal stress does not occur between sealing resin and a main body of a pressure detection device, wherein the detachment can cause insulation failure or pressure detection device corrosion due to external moisture penetration. The pressure sensor comprises: a joint member (14) including a fluid path (12); a pressure detection sensor (16) which is arranged to face the fluid path (12) of the joint member (14); an external lead wire (54) to which is connected to the pressure detection device; and a sealing resin unit (52) constituting an adhesive for filling a space formed inside a cover member (42), wherein the cover member (42) has a cylindrical shape including a part which is approximately vertical in a sealing resin containing unit (48) for holding the sealing resin unit. |
