PROBLEM TO BE SOLVED: To provide a hose 1 for a pressure sensor, capable of normally transmitting pressure by preventing closure of a hollow part of the hose 1 for a pressure sensor due to condensed water in a case where subject medium for pressure detection is gas. SOLUTION: Structure is provided in which hydrophilic members 2b and 2c are exposed in an inner wall surface that composes the hollow part of the hose 1 for a pressure sensor. In this hose 1 for a pressure sensor, condensed water, if any generated in the hose 1 for a pressure sensor, becomes wet to spread over the hydrophilic members 2b and 2c exposed in the inner wall surface. Closure of the hollow part in the hose 1 for a pressure sensor is thus prevented, and pressure is transmitted normally. The structure may otherwise be such that irregularities 2d-2f are provided in the inner wall of the hose 1 for a pressure sensor. In this case, surface tension of condensation water is broken by the irregularities 2d-2f provided in the inner wall of the hose 1 for a pressure sensor, thereby closure of the hollow part can be prevented.
