Abstract: Provided is an electronic component mounting structure and method for mounting electronic components on the side of a printed circuit board by means of simple fabrication and enlarging the surface area for mounting electronic components. A cut face of a conductive plating layer, which is obtained by cutting along a via in which a conductive plating layer covering an inner wall face of a via hole is electrically connected to a conductive pattern layer of the printed circuit board, is exposed at a cut end face and used as a land pattern which is solder-connected to a mount connecting portion of the electronic component. The end face at which the land pattern is exposed is a surface parallel to the side of the printed circuit board, and therefore electronic components can be mounted on the end face parallel to the side.
