Abstract: The biological information detection sensor supply device is provided with a main body case having a supply port to which a biological information measurement device can be attached, a housing unit for housing a biological information detection sensor and a sensor supply film including a cover film and a holding film for sandwiching the biological information detection sensor, and a supply unit for supplying the biological information detection sensor from the housing unit to the supply port. The supply unit supplies the biological information detection sensor to the supply port, and separates the holding film and the cover film from the sensor supply film in a state before the biological information detection sensor is supplied to the supply port. At the supply unit, the biological information detection sensor supplied to the supply port is fitted to the biological information measurement device fitted to the supply port.
