The object of the present invention is to provide a printed circuit board that improves the heat radiating effect as the entire printed circuit board and a manufacturing method for such a printed circuit board. A printed circuit board includes a base member having two main surfaces, at least one heat-radiating conductor layer formed on at least one of the main surfaces of the two main surfaces of the base member and a solder resist layer formed on a surface of the heat-radiating conductor layer, and in this printed circuit board, the heat-radiating conductor layer has two main surfaces and at least one side face, the heat-radiating conductor layer has its one main surface of the two main surfaces made in planar contact with the main surface of the base member, the solder resist layer further has an etching liquid resistance, and is formed on the other main surface of the two main surfaces of the heat-radiating conductor layer, with the side face of the heat-radiating conductor layer being exposed, and the heat-radiating conductor layer and the solder resist layer are allowed to form a laminate 24 having a substantially convex shape with an appropriate height.
