To provide an inclusion compound capable of stabilizing and controlling the release over a long period by including allyl isothiocyanate in high content, and a method for producing the compound.

The inclusion compound comprises diphenic acid bis(dicyclohexylamide) as a host compound, and the allyl isothiocyanate as a guest compound. The method for producing the inclusion compound involves bringing the diphenic acid bis(dicyclohexylamide) into contact with the allyl isothiocyanate. The diphenic acid bis(dicyclohexylamide) is dissolved in di-n-butyl ether by heating, and the allyl isothiocyanate is added to the solution to crystallize the product.
