PROBLEM TO BE SOLVED: To provide a precoated metal sheet superior in press formability, and a manufacturing method therefor. SOLUTION: The precoated metal sheet superior in press formability has a chemical conversion coating layer on one side or both sides, which contains, at least either of tannin or tannic acid, a silane coupling agent, and fine silica powders, altogether as solid contents, and further has a painted layer thereon, which contains an aluminum phosphate-based pigment of 1-140 pts.mass to a resin solid content of 100 pts.mass. The manufacturing method is also disclosed. The chemical conversion coating layer preferably further contains a polyester resin. The painted layer preferably further contains a rust preventive pigment. In addition, the aluminum phosphate-based pigment optimally includes aluminum dihydrogentripolyphosphate. The rust preventive pigment optimally includes calcium ion-exchangeable silica. COPYRIGHT: (C)2003,JPO
