A stretchable sensor that has excellent adhesion to a living body that is a detection target, has no burden of wearing, and can perform highly accurate measurement, and a physical condition management device using the sensor. A stretchable sensor for detecting biological information, comprising: a stretchable substrate; and an organic electroluminescent element provided on the substrate for irradiating a living body to be detected with light. It is characterized by comprising a light source and detection means comprising an organic photoelectric conversion element that is provided on the substrate and detects light from the light source reflected by the detection target.
