A biological information measuring system capable of measuring defecation gas containing a sulfur component with sufficient accuracy. A biological information measurement system, which includes a suction device 318 for sucking a gas in a bowl, a gas detection device 320 including a semiconductor gas sensor that reacts to odorous gas, a control device, and a physical condition of a subject. The semiconductor gas sensor 326 is disposed in the measurement gas passage 318b and includes a first detection unit 326a that detects gas in a state of being heated to a predetermined temperature. The sensor temperature control device for controlling the temperature of the first detection unit provided in the apparatus heats the first detection unit to the detection temperature during gas detection by the gas detection device, and after the gas detection is completed, The first detection unit is heated to a cleaning temperature higher than the detection temperature, and the adhering matter adhering to the first detection unit is removed.
