A process for producing an amide compound with the use of a nitrile hydratase of high thermal stability capable of maintaining high activity even in the presence of high-concentration nitrile compound as a substrate and amide compound as a product. A recombinant microbe was produced by searching for a novel microbe capable of expression of the desired nitrile hydratase in nature, obtaining relevant gene from cells of the microbe or treatment product thereof, performing cloning of the gene and introducing the same in a different type of microbe for expression. With the use thereof, nitrile compounds can be efficiently converted to corresponding amide compounds even by the reaction conducted at high temperature and in the presence of high-concentration nitrile compounds and high-concentration amide compounds.
