Zusammenfassung:	Cluster-supporting catalyst having an improved heat resistivity, and method for producing the same are provided. The cluster-supporting catalyst of the present invention comprises boron-substitute zeolite particles (20), and catalyst metal clusters (16) supported within the pores of the boron-substitute zeolite particles. The method of the present invention for producing a cluster-supporting catalyst, includes the following steps: providing a dispersion liquid containing a dispersion medium and boron-substitute zeolite particles (20) dispersed in the dispersion medium; and in the dispersion liquid, forming catalyst metal clusters (16) having a positive charge, and supporting the catalyst metal clusters on the acid sites within the pores of the boron-substitute zeolite particles through an electrostatic interaction.
