Abstract
Provided is a sliding component having a low coefficient of friction and capable of exerting stable sliding characteristics from the initial stage of sliding, and a manufacturing method capable of easily manufacturing the sliding component. A sliding component () includes an iron substrate (), in which graphite particles () are dispersed in an iron base (), and a tin coating () formed on the iron substrate (), the tin coating () including tin as a main material. The graphite particles () of the sliding component () are exposed through the tin coating (). The manufacturing method includes: a preparation step of preparing an iron substrate () including graphite particles () dispersed in an iron base (); 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 forms the tin coating () so that the graphite particles () are exposed through the tin coating ().
