There are provided a structured catalyst for fluid catalytic cracking having an excellent catalytic activity, which ensures achieving the satisfactory catalytic activity over a long period of time by suppressing aggregation of catalytic substances, a fluid catalytic cracking device including the same, and a method for producing a structured catalyst for fluid catalytic cracking. The structured catalyst for fluid catalytic cracking includes a support having a porous structure composed of a zeolite-type compound and at least one catalytic substance present inside the support. The support includes channels connecting with one another. The catalytic substance is one of metal nanoparticles and a solid acid. The catalytic substance is present in at least the channel of the support. When the catalytic substance is the metal nanoparticles, the metal nanoparticles are metal nanoparticles of at least one type selected from the group consisting of nickel, cobalt, iron, copper, gold, silver, platinum, palladium, rhodium, iridium, ruthenium, osmium, and molybdenum.
