The present invention provides a recovery method in which the indium sponge that is deposited by substitution in the substitution deposition step in the recovery of indium from an indium-containing material is produced in the form of a powder rather than in a bulky form. This recovery method is a method in which an indium sponge is deposited by substitution by adding a substance containing chlorine, and further adding a reducing agent, to an indium-containing solution whose pH has been adjusted to a value in the range of 1 to 2.2.
