A pressure sensor (10) is provided, which includes a pressure detector (20) that has a pressure receiving surface (15) in contact with a liquid, and detects a pressure of the liquid to a pressure receiving section (16) included in the pressure receiving surface (15), and a housing (14) having a housing inner wall (19) that demarcates a liquid chamber (11) together with the pressure receiving surface (15), wherein the housing inner wall (19) is provided with an inflow hole that causes the liquid to flow into the liquid chamber (11), and an outflow hole that causes the liquid to flow out of the liquid chamber (11), at least a part of a connecting portion, which is connected to the pressure receiving surface (15), of the housing inner wall (19) is formed as an inner wall of the outflow hole, and the housing inner wall (19) at the portion formed as the inner wall of the outflow hole protrudes more outward of the liquid chamber (11) than the other connecting portion adjacent to the portion formed as the inner wall of the outflow hole. |
