To provide a resin coated metal plate and a method of manufacturing a printed circuit board using the resin coated metal plate suitable as a guide plate for drilling the printed circuit board with high effects of preventing the heat generation of a drill bit, lubrication and preventing the scatter of chips, and excellent chip discharging ability to permit the drilling of high quality of high efficiency with excellent smoothness on the internal wall of a machined hole in drilling the printed circuit board by a drill, and further with the low breakage of the drill and excellent working efficiency and storage stability without stickiness.

This resin coated metal plate can achieve the solution of the problems by appropriately specifying the water solubility, melting point, melting viscosity and hardness of coating resin.
