This coated steel sheet (10) is configured such that a steel sheet (11) and a coating film (14) are laminated in this order. The coating film (14) contains a polyimide (141) and a cured silicone (144). The area occupancy of the cured silicone (144) in the surface of the coating film (14) is 5% or more. The coated steel sheet (10) has both excellent heat resistance and excellent antifouling properties, and is suitable for use as a material for members for cooking utensils. 本发明的涂装钢板(10)通过依次重叠钢板(11)和上涂涂膜(14)而构成。上涂涂膜(14)包含聚酰亚胺(141)及固化硅酮(144)。上涂涂膜(14)的表面中的固化硅酮(144)的占有面积率为5％以上。涂装钢板(10)的耐热性和防污性这两者优异，适宜作为烹调器具用部件的材料使用。
