To provide material which has a large effect of deodorizing various kinds of malodor components, in particular, malodor components of sulfur-based gas such as hydrogen sulfide, methyl mercaptan by solving the problem of a conventional deodorant.

This deodorant is completed by finding that amorphous metal silicate having specific physical property has excellent deodorization performance to the malodor component of sulfur-based gas. That is, this deodorant is a sulfur-based deodorant which is an amorphous compound of at least one kind of metal salt selected from copper, zinc, manganese, cobalt and nickel, and silicate, and which has a pore volume of 0.3 to 0.5 ml/g.
