[PROBLEMS] To decompose and deodorize a vaporized chemical substance by a photocatalytic function, and to adsorb and deodorize a chemical substance exceeding the decomposing ability to the pores. When saturated, by exposing to sunlight, etc., the chemical substances in the pores can be decomposed by the photocatalytic function to restore the adsorption capacity and maintain the adsorption capacity of chemical substances, etc. Of adsorbents with high decomposition performance that excel in the efficiency, certainty, and stability of adsorption and decomposition. A granular material comprising: a granular material formed of a porous material having micropore or mesopore pores; and a thermal spray coating formed by spraying a thermal spray material containing photocatalyst particles on the outer surface of the granular material. A gap larger than the pores is formed between the photocatalyst particles sprayed on the outer surface and the outer surface of the granular material, and between the photocatalyst particles deposited by thermal spraying.
