  • Patent number: 9516749
    Abstract: Disclosed is an electronic component-mounted structure including: a substrate, a conductive wiring pattern formed on a surface of the substrate, and an electronic component having an external terminal and being placed on the surface of the substrate at a mounting position including a terminal joint position of the conductive wiring pattern. The external terminal is joined to the conductive wiring pattern at the terminal joint position such that the external terminal is embedded in the conductive wiring pattern. Therefore, the junction between the external terminal and the conductive wiring pattern can have a high strength as compared with that obtained by joining the external terminal of the electronic component to the conductive wiring pattern merely on the surface of the conductive wiring pattern.
