PROBLEM TO BE SOLVED: To provide a hydrogen separation membrane module, a hydrogen refining apparatus, and a hydrogen extraction method capable of increasing further hydrogen permeation efficiency. SOLUTION: This hydrogen separation membrane module 10 is provided with a hydrogen separation membrane 200, a supply passage plate 100 forming a supply gas passage 130 for reducing the velocity of hydrogen-containing gas from the upstream side to the downstream side, and a recovering passage plate 300 forming a recovered gas passage 330 for increasing the velocity of purge gas from the upstream side to the downstream side.
