PROBLEM TO BE SOLVED: To provide a hydrogen separation member used for separating hydrogen gas in a gaseous mixture with hydrogen by allowing the hydrogen gas to selectively permeate the member, and to provide a manufacturing method of the hydrogen separation member. SOLUTION: The hydrogen separation member is provided with: a cylindrical acceptor member made of a metal sintered body which is gas-permeable and porous; a hydrogen permeable membrane which wraps the acceptor member and allows hydrogen gas to selectively permeate the member from gaseous mixture with hydrogen; and an outer porous body which is arranged outside the hydrogen permeable membrane and covers and protects the hydrogen permeable membrane, wherein an intermediate layer made of fine powder is disposed between the hydrogen permeable membrane and the outer porous body.
