Deterioration of a mechanical property with time is suppressed even in a case of usage in an underwater environment for a long time. An underwater sliding member of the present embodiment is an underwater sliding member used under water, and has: a base material 11 made of a first metal material; an intermediate layer 12 of a porous structure joined to the base material 11 and made of a second metal material; a corrosion inhibiting layer 122 a part of which is melted and filled into a hole of the porous structure of the intermediate layer 12; and a sliding layer 13 formed on the corrosion inhibiting layer 122 and made of a resin material.
