description Disclosed is a printed wiring board offering improved reliability through increased mechanical strength at the bottom of cavity areas for mounting components. A printed wiring board 10 is characterized in that an insulation layer 16 is formed on either the top or bottom side of a metal core 11, while an opening 12 formed in the metal core 11 is used as a cavity area 15a for mounting a component, wherein a reinforcement pattern 30 is formed on the surface of an insulation layer facing the bottom of the cavity area 15a in the insulation layer 16. The reinforcement pattern 30 is made of the same material as the wiring patterns 28c, 29c formed on the insulation layer 16, and also formed simultaneously with these wiring patterns 28c, 29c.
