PROBLEM TO BE SOLVED: To provide an environmental atmosphere concentration recording device capable of measuring and recording easily the environmental atmosphere concentration inside or outside a building or around a moving object, a man or the like, and an environmental atmosphere concentration data collection system capable of real-time measurement. SOLUTION: This device is equipped with a sensor wherein the length of a discoloring layer is changed by an influence of the environment, a measuring means for measuring the length of the discoloring layer of the sensor, and a recording device for converting the length of the discoloring layer measured by the measuring means into the environmental atmosphere concentration and recording it. The sensor is a detection tube 1 filled with a material discoloring by a reaction with the environmental atmosphere, and the measuring means is one reflection type photosensor 2 for measuring the length of the discoloring layer of the sensor.
