PROBLEM TO BE SOLVED: To provide a material which has a large effect of deodorizing the malodor components of various kinds of sulfur-based gas, in particular, the components such as hydrogen sulfide by solving the problem of a conventional deodorant. SOLUTION: This deodorant is achieved by finding that amorphous metal silicate having specific physical property has excellent deodorization performance to the malodor component of sulfur-based gas. That is, a sulfur-based gas deodorant is constituted of amorphous metal silicate salt where an elemental composition (mole) ratio between silicon and at least one kind of metal selected among copper, zinc, manganese, cobalt and nickel is within the range of 0.60-0.80, and also crush strength is within the range of 1-3N.
