1. A support and metal catalyst, comprising:
a support powder; and
metal fine particles supported on the support powder; wherein:
the support powder is an aggregate of support fine particles;
the support fine particles have a chained portion structured by a plurality of crystallites being fusion bonded to form a chain;
the support fine particles are structured with metal oxide; and
the metal oxide comprises titanium and tin at an atomic ratio of titanium with respect to total of titanium and tin of 0.30 to 0.80;
the metal oxide is doped with a dopant element having a different valence than the titanium and tin.
