description This surface-treated metal sheet comprises: a steel sheet; a plating layer that is formed on the steel sheet and contains zinc; and a coating film that is formed on the plating layer. With respect to this surface-treated metal sheet, the coating film contains an organosilicon compound, a phosphoric acid compound, and a fluorine compound. With respect to the surface roughness of a 1 μm square area of the surface of the coating film, if Sa is the arithmetic mean height, Sz is the maximum height and Sq is the root mean square roughness, one or more of the following conditions are satisfied: the arithmetic mean height Sa is from 0.1 nm to 10 nm; the maximum height Sz is from 1 nm to 1,000 nm; and the root mean square roughness Sq is from 0.1 nm to 100 nm. La presente invención se refiere a una lámina de metal de superficie tratada incluye una lámina de acero, una capa de recubrimiento que contiene zinc formado en la lámina de acero y un recubrimiento de conversión formada sobre la capa de recubrimiento, en donde el recubrimiento de conversión contiene un compuesto de organosilicio, un compuesto de fosfato y un compuesto de flúor, y cuando la rugosidad de la superficie en un área rectangular con un lado de 1 µm en la superficie del recubrimiento de conversión está representada por un altura media aritmética de la superficie limitada a escala Sa, una altura máxima de la superficie limitada a escala Sz, y una altura cuadrática media de raíz de la superficie limitada a escala Sq, una o más condiciones de una altura media aritmética de la superficie limitada a escala Sa siendo de 0.1 a 10 nm, una altura máxima de la superficie limitada a escala Sz siendo 1 a 1,000 nm, y una altura cuadrática media de raíz de la superficie limitada de escala Sq ser Se satisfacen de 0.1 a 100 nm.
