PROBLEM TO BE SOLVED: To provide a flow velocity sensor capable of measuring a flow velocity in a river or the like accurately with a simple constitution without providing a complicated constitution such as a mechanical driving part or a strain generation part. SOLUTION: In this flow velocity sensor, heating plates 2 are stuck on both surfaces of a heater 3 provided with a heater electrode 5, and an FBG 4 connected to a sensor cable 1 is fixed on the heating plate 2 with an epoxy resin, and the heater 3, the heating plate 2 and the FBG 4 are molded integrally with a waterproof material by a waterproof mold 6.
