Zusammenfassung:	The objective is to provide a roller bearing equipped with a coating having excellent rust prevention capability and capable of being used for a long period in a highly corrosive environment. This roller bearing 1 is used in a power generator or power generation equipment that generates electricity from natural energy. For the one or more bearing members forming the bearing, a rust prevention coating is formed in a prescribed region of the surface of a base material, and the rust prevention coating forms a porous coating in that entire region having a sacrificial anode effect with respect to the base material. A sealing process in which a sealing agent is impregnated from the surface of the porous coating is performed with respect to the porous coating in a portion of that region or the porous coating in the entire region, a first coating process is performed, in which the sealed body obtained by performing the sealing process on the porous coating is covered with an epoxy resin paint, and a second coating process is performed, in which the coated surface obtained with the first coating process is covered with a urethane resin paint. The sealing agent is obtained by diluting the epoxy resin paint with a dilution ratio of 15-25%. La présente invention a pour objet de concevoir un roulement à rouleaux équipé d'un revêtement ayant une excellente capacité de prévention contre la rouille et pouvant être utilisé pendant une longue période dans un environnement hautement corrosif. Le présent roulement à rouleaux 1 est utilisé dans un générateur de puissance ou un équipement de génération de puissance qui génère de l'électricité à partir d'une énergie naturelle. En ce qui concerne le ou les éléments de roulement formant le roulement, un revêtement de prévention contre la rouille est formé dans une région prescrite de la surface d'un matériau de base, et le revêtement de prévention contre la rouille forme un revêtement poreux sur toute la région assurant un effet d'anode protectrice par rapport au matériau de base. Un traitement d'étanchéité est appliqué, selon lequel un agent d'étanchéité est imprégné à partir de la surface du revêtement poreux par rapport au revêtement poreux d'une partie de la région ou par rapport au revêtement poreux de toute la région, un premier traitement de revêtement est appliqué, selon lequel le corps étanché obtenu par l'application du traitement d'étanchéité au revêtement poreux est recouvert d'une peinture à base de résine époxy, et u
