Claim Text:
1. A mounting structure, comprising: a substrate which has an electrode; an electronic component which has an electrode; a joint which is shaped like a square and connects the electrode of the electronic component and the electrode of the substrate, and which is made of a metal nanoparticle paste material; and a plurality of convex portions which are provided within the metal nanoparticle paste material of the joint between the electrode of the electronic component and the electrode of the substrate, wherein the plurality of convex portions are all provided at a central portion of the joint but are not provided at a peripheral portion of the joint such that the convex portions are closer to a center of the joint than they are to all edges of the joint, and are made of a material with a higher thermal conductivity compared with the metal nanoparticle paste material.
