To obtain a humidity measurement device capable of determining whether a value detected by a humidity sensor is valid, a humidity measurement device according to the present invention, which measures the humidity of the intake air of an internal combustion engine (2), has a water droplet adhesion determination means (51) for determining, on the basis of changes in the intake air humidity and temperature, whether water droplets are adhered to the surface of a sensor element (22) of a humidity sensor (21) for sensing the humidity. As a result, it is possible to determine whether a value detected by the humidity sensor (21) is valid. |
