An adhesive layer 3 is disposed between a carbon particle 2 and a catalyst substance 1 of a catalyst-supporting particle for a fuel cell containing the carbon particle 2 and the catalyst substance 1. Thereby, the catalyst-supporting particle for fuel cell can be obtained in which a contact resistance between the catalyst substance and the carbon particle supporting the same is lower, and the aggregation of the catalyst substance is suppressed. A catalyst electrode for a fuel cell and the fuel cell using the above particle have a higher output power and an excellent durability.

1. A catalyst-supporting particle for a fuel cell comprising a carbon particle, catalyst metal supported on the carbon particle, and an adhesive layer disposed between the carbon particle and the catalyst metal, wherein the adhesive layer consists of one or more elements selected from the group consisting of Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W, Mn, Fe, Co and Ni and the adhesive layer forms a carbide with the carbon particle; andwherein the catalyst metal contains platinum group metal or its alloy. 2. The catalyst-supporting particle for the fuel cell as defined in claim 1, wherein the adhesive layer consists of one or more elements selected from the group consisting of Ti, Zr and Hf. 3. The catalyst-supporting particle for the fuel cell as defined in claim 1, wherein the adhesive layer consists of one or more elements selected from the group consisting of Mn, Fe, Co, Ni. 4. The catalyst-supporting particle for the fuel cell as defined in claim 1, wherein the adhesive layer contains a transition metal element.
