The present invention discloses a combined printed circuit board and a method for manufacturing the printed circuit board. The method for manufacturing the printed circuit board of the embodiment of the present invention comprises the steps of forming a first opening penetrating a first conductive layer and a dielectric layer at the positions at which through holes need to be formed on the first conductive layer coated with a metal plate and the dielectric layer; forming a second opening penetrating a second conductive layer at the corresponding position of the second conductive layer coated with a metal plate, wherein the first opening and the second opening at the corresponding position form a superimposed through hole, the caliber of the first opening is same as a preset aperture of the corresponding through hole and is greater than the caliber of the second opening at the corresponding position; filling a conductive paste in the superimposed through hole to obtain the combined printed circuit board. According to the combined printed circuit board manufactured by the method of the embodiment of the present invention, the caliber of the second opening is less than the caliber of the first opening, so that the residual conductive paste at the second opening can be reduced effectively, and accordingly, the manufacture cost is reduced.
