1. A method for manufacturing a sliding component, comprising:
a preparation step of preparing an iron substrate including graphite particles dispersed in an iron base, the graphite particles being exposed on a surface; and
a film forming step of forming a tin coating on the surface of the iron substrate, the tin coating including tin as a main material,
the film forming step forming the tin coating so that the graphite particles are exposed through the tin coating, and
the film forming step projecting tin particles including tin as a main material to a surface of the iron base to let a part of the tin particles adhere to the surface of the iron base where the graphite particles are not exposed.
