PROBLEM TO BE SOLVED: To provide a metal plate for a printed circuit board such as, for example, a printed circuit board for use in a vehicle, maintaining high durability and reliability of joining between a resin base material for the printed circuit board and the metal plate for the printed circuit board even under extremely severe environments of temperature and humidity. SOLUTION: The metal plate 1 for the printed circuit board is clad with the plate-shaped resin base material 2 for the printed circuit board. The metal plate 1 has a maximum thickness of 100μm or more. A groove 3 is formed in a surface thereof clad with the resin base material 2 to have an average surface roughness of 1.0μm or more and 10μm or less at ten points on the surface and fine particles 4 having the grain size of 0.2μm or more and 4.0μm or less are bonded to the surface.
