Mounting structure of electronic component, electro-optic device, electronic equipment, and method for mounting electronic component

摘要

To provide a low cost mounting structure of an electronic component and to increase the reliability of the conductive connection between a bump electrode and a terminal formed on a substrate, in the mounting structure of the electronic component, the bump electrode includes a core composed of an inner resin and a conductive film covering the surface of the core. The bump electrode is brought into conductive contact with the terminal directly and is elastically deformed to make contact with the face of the substrate in a planar manner. A sealing resin is filled in around the conductive contact portion between the bump electrode and the terminal to hold the bump electrode and the terminal.
