La présente invention a pour but d'améliorer l'efficacité de génération d'énergie d'une génération d'énergie marémotrice, et de fournir ainsi un générateur d'énergie marémotrice qui capture avec une meilleure efficacité l'énergie de l'écoulement de l'eau de mer. Pour atteindre ce but, l'invention porte sur un générateur d'énergie marémotrice qui est caractérisé en ce qu'il est pourvu : d'un corps rotatif sous-marin qui tourne en conséquence de l'impact d'un courant de marée qui s'écoule d'un côté amont à un côté aval ; d'un générateur d'énergie qui génère de l'énergie sur la base du couple du corps rotatif ; d'un dispositif de guidage qui est positionné en dessous du corps rotatif sous-marin et qui possède une surface inclinée qui guide le courant de marée, de telle sorte que celui-ci s'écoule vers le corps rotatif.
