Abstract
A resin-coated metal sheet for a container, the metal sheet including: a first resin coat layer provided on a first surface of the metal sheet; a second resin coat layer provided on a second surface of the metal sheet, wherein each of the first and the second resin coat layers is composed mainly of a polyester resin having a melting point of 230° C. to 254° C., and the first resin coat layer, in a state that the resin coat layers coat the metal sheet, is formed of a resin material having: an arithmetic average roughness (Ra) of 0.10 μm to 1.0 μm; a crystallization temperature of 110° C. to 160° C.; and a water contact angle of 55 degrees to 80 degrees in a state that the resin coat layers have been heated at 240° C. for 90 seconds after the resin coat layers coat the metal sheet.
