PROBLEM TO BE SOLVED: To provide a weather measuring device having a simple configuration, capable of not only performing accurate measurement relative to rainfall but also collecting correlatively various information on the weather of rain such as the size of rain droplets or dropping speed of the rain droplets, and measuring the weather such as snow or fog. SOLUTION: This device is equipped with a light source 6; a collimating lens 7 for collimating light emitted from the light source 6 into parallel light L2 proceeding to a prescribed direction C; a condensing lens 8 arranged separately from the collimating lens 7 at a fixed distance in the prescribed direction C; and an image sensor 4 for receiving light from the condensing lens 8, and outputting image data of rain droplets, snow particles, fog particles or the like in the air passing between the lenses.
