Abstract
A high heat-resistant catalyst includes: noble metal particles; first compounds which contact the noble metal particles and suppress movement of the noble metal particles; and second compounds which envelop the noble metal particles and the first compounds, suppress the movement of the noble metal particles, and suppress coagulation of the first compounds following mutual contact of the first compounds. The first compounds support the noble metal particles, and single piece or aggregate of the first compounds supporting the noble metal particles are included in a section partitioned by the second compounds. A coefficient of linear thermal expansion of the second compounds is 1.2×10[K] or less.
