The present invention provides a filling valve which affords an excellent sterilization capability and a high maintenance capability. The valve includes a tubular nozzle 4 , an operating rod 6 which is fitted in the nozzle 4 so as to be elevatable, and an opening/closing valve 22 formed by a valve seat 10 a on the internal surface of the nozzle 4 at its bottom end and a valve element 6 a formed at the bottom end of the operating rod 6 . A portion 10 c of a reducing diameter which gradually reduces the cross-sectional area of the filled liquid passage 10 in a downward direction and a portion 10 e of an increasing diameter which gradually increases the cross-sectional area of the filled liquid passage 10 in the downward direction are formed on the internal surface of the nozzle 4 at an upper portion thereof. A plurality of straightening vanes 36 are formed on the internal surface of the nozzle 4 at a location below the portion 10 e of an increasing diameter.
