Zusammenfassung:	To provide a double-pipe catalytic reaction pipe and a hydrogen production apparatus capable of suppressing the wear of a catalyst due to thermal expansion.SOLUTION: A double-pipe catalytic reaction pipe 100A has an outer pipe 10, an inner pipe 20 arranged concentrically about the outer pipe 10, and a catalyst 30 packed between the outer pipe 10 and the inner pipe 20. The double-pipe catalytic reaction pipe brings a raw material gas G1 into contact with the catalyst 30 for a chemical reaction. The inner pipe 20 is covered with a first sleeve 50. According to the present invention, the wear of the catalyst due to thermal expansion can be suppressed.SELECTED DRAWING: Figure 2A 【課題】熱膨張に起因する触媒の摩損を抑制できる二重管型触媒反応管及び水素製造装置を提供する。【解決手段】本発明の二重管型触媒反応管は、外管１０と、外管１０に対して同芯に配置された内管２０と、外管１０と内管２０との間に充填された触媒３０と、を備え、原料ガスＧ１を触媒３０に接触させて化学反応させる二重管型触媒反応管１００Ａであって、内管２０は、第１スリーブ５０に覆われるものである。本発明によれば、熱膨張に起因する触媒の摩損を抑制できる。【選択図】図２Ａ
