A substrate processing method includes holding a substrate; and supplying an etching liquid to the substrate held in the holding of the substrate. The etching liquid contains an etching agent configured to etch a metal-based first material and a silicon-based second material exposed on the substrate and a protection agent configured to react with the second material between the first material and the second material to form a protection layer on a surface of the second material. Here, the etching agent is a liquid which contains fluorine atoms and an organic solvent and substantially does not contain water, and the protection layer protects the second material from etching with the etching agent.
