Beschreibung
Zusammenfassung:	A three-dimensional structure (10); and a catalytic component (100) that contains a precious metal complex (22) containing platinum and palladium and a porous material (21), which is supported on the three-dimensional structure (10); where the surface accumulation C (Pt) of the platinum is 0.00070 or more to 0.01000 or less, the surface accumulation C (Pd) of the palladium is 0.00800 or more to 0.10000 or less, the surface accumulation C (Pt) is expressed by C (Pt) = PXPS (Pt) / (d2 × PTEM (Pt) × 0.01), and the surface accumulation C (Pd) is expressed by C (Pd) = PXPS (Pd) / (d2 × PTEM (Pd) × 0.01).
