A needle-type fluorescence sensor that measures glucose based on fluorescence produced by excitation light is provided. The needle-type fluorescence sensor includes a needle body section including a sensor portion disposed in a needle distal end portion and metal lines disposed from the sensor portion to a needle proximal end portion, and a connector which is integrated with the needle body section and in which the metal lines extend. The sensor portion includes a silicon substrate having first and second principal surfaces, a PD device that converts fluorescence into an electric signal, an LED device that transmits fluorescence and emits excitation light, and an indicator layer that interacts with an analyte under the excitation light to produce fluorescence. The PD device, the LED device, and the indicator layer overlap with each other above the first principal surface of the silicon substrate. |
