Pre-coated metal sheet, burn prevention cover, and method for manufacturing pre-coated metal sheet

Even if the coating film is subjected to pressure during storage, transportation and press processing, gaps in the coating film are maintained. This precoated metal plate is provided with: a metal plate; and a void-containing coating film which is located on at least one surface of the metal plate, in which fine particles are dispersed, and which has voids, the voids being 40-95% by area relative to the total area of the cross-section of the void-containing coating film when the cross-section obtained by cutting the void-containing coating film in the thickness direction of the void-containing coating film is observed. When the average particle diameter of the fine particles is t [[mu] m] and the average film thickness of the void-containing coating film is T [[mu] m], the ratio t/T is in the range of 0.7-3.0, and the elastic modulus when the fine particles are compressed by 10% from the thickness direction is 30 MPa or more. 即使在保管、输送时和压制加工时涂膜受到压力，也保持涂膜中的空隙。本发明的预涂金属板具备：金属板；和含空隙涂膜，其是位于前述金属板的至少一个面上的、分散有微粒并且具有空隙
