An object of the present invention is to provide an artificial liver using highly functional hepatocytes. There is provided an extracorporeal artificial liver having at least one module comprising the followings: a plasma ingredient inlet port, and a plasma ingredient outlet port; a plasma ingredient circulation chamber having the plasma ingredient inlet port, and the plasma ingredient outlet port; and a hepatocyte culture chamber provided adjacently to the plasma ingredient circulation chamber and separated from the plasma ingredient circulation chamber with a separation membrane through which ammonia can permeate, but hepatocytes cannot permeate, in which hepatocytes having an ammonia-metabolizing ability are cultured.
