1. A structured catalyst for steam reforming used for producing, from a reforming raw material containing hydrocarbon, reformed gas containing hydrogen, the structured catalyst comprising:
a support having a porous structure constituted of a zeolite-type compound; and
at least one catalytic substance present inside the support, wherein
the support includes channels connecting with each other, and
the catalytic substance is metal nanoparticles and present at least in the channels of the support, wherein
the channels include any one of a one-dimensional pore, a two-dimensional pore, and a three-dimensional pore defined by a framework of the zeolite-type compound and a plurality of enlarged pore portions having a diameter different from that of any of the one-dimensional pore, the two-dimensional pore, and the three-dimensional pore,
the metal nanoparticles are embedded in a respective enlarged pore portion such that a metal nanoparticle is separate from another metal nanoparticle of the metal nanoparticles, and
the average inner diameter of the channels is less than the inner diameter of the enlarged pore portion.
