A method for manufacturing a rigid-flexible printed wiring board is provided to obtain stable peeling strength by performing washing with calcium added water after an alkali-treatment. A method for manufacturing a rigid-flexible printed wiring board includes the steps of: treating both outer surfaces of an inner layer FPC(Flexible Printed Circuit)(30) with alkali; and respectively stacking outer layer RPCs(Rigid Printed Circuits)(50A,50B) on the both outer surfaces of the inner layer FPC through adhesive members(40A,40B). The method for manufacturing the rigid-flexible printed wiring board further includes the step of: washing the both surfaces of the alkali-treated inner layer FPC with calcium added water between the two steps.
