PROBLEM TO BE SOLVED: To provide a fluorocarbon resin-coated metallic sheet having embossed external appearance having high design properties. SOLUTION: This method for manufacturing fluorocarbon resin-coated metallic sheet comprises the steps of: forming a primer coating film on a base metallic sheet on which coating pretreatment is performed; applying polyvinylidene fluoride/acrylic resin-based coating, in which a pigment and an additive is blended, to the upper surface of the primer coating film, so that the dried film thickness becomes 10-30μm; heat-treating the coating-applied metallic sheet at the temperature equal to or higher than the melting point of the coating; pressing the heat-treated metallic sheet by an embossed roll while keeping the temperature equal to or higher than the melting point of the coating; and rapidly cooling the embossed metallic sheet to fix an embossed pattern.
