Painted metal plate and method for producing same

A coated metal sheet, comprising:

• a metal sheet;
• and a fluorinated coating film formed on the metal sheet, wherein
• the coating film contains a cured product of a silicone resin, and a fluorine-containing resin;
• an amount of the cured product of the silicone resin is 1 to 10 parts by mass of a total mass of the coating film;
• the silicone resin contains Si atoms derived from trialkoxysilane in an amount of 50 to 100 mol % relative to the total number of moles of Si atoms;
• a weight average molecular weight of the silicone resin is 1000 to 10000;
• when a surface of the coating film is analyzed with X-ray electron spectroscopy using an A1Kα ray as an X-ray source, Sia and x satisfy the following expressions respectively, wherein Sia is a proportion of Si atoms based on a total amount of Si atoms, F atoms, C atoms, and O atoms, and x is a ratio of an amount of O atoms to an amount of C atoms:
• Sia≥8 atm %
• x≥0.8;
• and
• when a C1s peak top in an X-ray photoelectron spectroscopic spectrum obtained through the analysis with X-ray electron spectroscopy is corrected to be 285 eV and a Si2p spectrum is separated into a peak corresponding to 103.5 eV and a peak corresponding to 102.7 eV, y satisfies the following expression, wherein y is a ratio of a peak area of 103.5 eV to a peak area of the entire Si2p spectrum:
• y≥0.6.
