Abstract: A production method comprises the steps of obtaining a mixed slurry by adding an alumina component and at least one selected from an alumina component and a clay mineral to a binder containing a silicon oxide; obtaining a metal trapping precursor by mixing the mixed slurry with a compound of a first metal component and heating the mixed slurry of metal component; and obtaining a metal trapping by drying and calcining the metal trapping precursor. A metal trapping comprises: a binder mainly containing silicon oxide, one or two selected from an alumina component and a clay mineral, and an oxide of a first metal component; having no peak of silicate of the first metal component detected in X-ray diffraction analysis, having an attrition resistance index CAI within a predetermined range. A fluid catalytic cracking catalyst comprises the metal trapping, a zeolite component, a binder component, and a clay mineral component.
