Abstract: The purpose of the present invention is to realize a dew point measurement in which the generation of dew condensation is directly detected and the detection can be performed without using any optical system. In particular, the purpose of the present invention is to realize a dew point measuring device that is compact and has a high sensitivity. According to one embodiment of the present invention, a sudden change in current values before and after the dew point is detected by detecting the dew condensation to detect a galvanic current that flows due to a water droplet attached onto a surface of an insulating substrate on which thin wires of dissimilar metals are juxtaposed, and by controlling the temperature on the surface of the substrate. In this way, the dew point measurement in which the dew point can be directly measured and a measurement with simple configuration and high accuracy can be performed can be realized.
