An anti-vibration rubber member includes: a rubber elastic body that is made of a self-lubricating rubber containing an elastomer and a bleeding lubricant; a coating film that covers at least a portion of a sliding inner surface that is a surface of the rubber elastic body disposed on an inner side of a sliding surface, contains a resin having a mercapto group and a solid lubricant containing polytetrafluoroethylene particles and ultrahigh molecular weight polyethylene particles, and is deformable to follow up deformation of the rubber elastic body; and a lubricating film that covers at least a portion of a surface of the coating film, is formed by including the bleeding lubricant having penetrated the coating film from the rubber elastic body and oozing onto the surface of the coating film, and forms at least a portion of the sliding surface.
