摘要： [Problem] To provide: a resin-coated metallic plate which cannot undergo the occurrence of a retort brushing phenomenon (the formation of white spots) or the delamination of a film under retort sterilization treatment conditions; and others. [Solution] A resin-coated metallic plate having a resin layer (A) and a resin layer (B) is characterized in that the resin layer (A) contains 50 to 80 wt % of a polyethylene terephthalate-based resin (I) and 20 to 50 wt % of a polybutylene terephthalate-based resin (II), wherein the resin layer (B) contains 50 to 80 wt % of a polyethylene terephthalate-based resin (III) and 20 to 50 wt % of a polybutylene terephthalate-based resin (II), the polyethylene terephthalate-based resin (I) has a melting point of 210 to 230° C. inclusive, the polybutylene terephthalate-based resin (II) has a melting point of 215 to 225° C. inclusive, and the polyethylene terephthalate-based resin (III) has a melting point of higher than 230° C. and 205° C. or lower.
