A voltage regulator module with a vertical layout structure includes a circuit board assembly, an electroplated region and a magnetic core assembly. The circuit board assembly includes a printed circuit board and at least one switch element. The printed circuit board includes a first surface, a second surface, a plurality of lateral surfaces, an accommodation space and a conductive structure. The switch element is disposed on the first surface. A conduction part is formed on the second surface. The conductive structure is perpendicular to the printed circuit board and disposed within the accommodation space. The electroplated region is formed on the corresponding lateral surface, arranged between the conduction part and the first surface, and electrically connected with the conduction part and the switch element. The magnetic core assembly is accommodated within the accommodation space. Consequently, an inductor is defined by the conductive structure and the magnetic core assembly collaboratively.
