Abstract: Provided is a wearable sensor with enhanced light sensitivity. The wearable sensor is to be worn by a subject, the wearable sensor including: a supporting substrate; and sensor elements placed on the supporting substrate. The sensor elements each include: a light emitter which is an organic light emitting diode or an inorganic light emitting diode; and a reflected light receiver configured to measure a quantity of light emitted from the light emitter and reflected in a living body of a subject. Preferably, in a plan view, at least part of the reflected light receiver does not overlap the light emitter.
