Claim:
1. A manufacturing method of a metal catalyst-supporting carrier in which a metal catalyst is supported on a carrier, the manufacturing method comprising: (a) a process of placing the carrier in a processing chamber, filling the processing chamber with a supercritical fluid and dispersing a complex of the metal catalyst in the supercritical fluid; (b) a process of controlling at least one of a temperature of the carrier and an ambient temperature in the processing chamber, so as to make a temperature difference of or above a predetermined amount between the temperature of the carrier and the ambient temperature, subsequently reduce the temperature difference between the temperature of the carrier and the ambient temperature at least once and then increase the temperature difference; and (c) a process of changing state of the supercritical fluid to a non-supercritical state and subsequently causing the metal catalyst to deposit on surface of the carrier.
