1. A metal trapping comprising:
a binder component containing 50 mass % or more silicon oxide,
one or two selected from an alumina component and a clay mineral, and
a compound comprising Group II elements as a first metal component, wherein
the binder component is at least one of an aqueous solution and fine particles (sol) having an average particle size in the range of 4 to 100 nm,
the content of the first metal component in terms of oxide is 20 to 80 mass %,
the metal trapping has no peak of silicate of the first metal component detected in X-ray diffraction analysis, and has an attrition resistance index CAI of 0.1 to 18.
