This invention provides a multilayer printed wiring board in which electric connectivity and functionality are obtained by improving reliability and particularly, reliability to the drop test can be improved. No corrosion resistant layer is formed on a solder pad 60B on which a component is to be mounted so as to obtain flexibility. Thus, if an impact is received from outside when a related product is dropped, the impact can be buffered so as to protect any mounted component from being removed. On the other hand, land 60A in which the corrosion resistant layer is formed is unlikely to occur contact failure even if a carbon pillar constituting an operation key makes repeated contacts.
