NOVELTY - An electroconductive ink comprises one or more aromatic resins, electroconductive silver particles, and one or more organic solvents. The electroconductive silver particles have an average particle size of 1-40 mu m, and a tap density of 1.5-6.5 g/cm3.    USE - Electroconductive ink is used in preparation of dried product used for formation of electroconductive pathway on substrate used for forming bonded assembly in fabrication of electronic device e.g. solar module (all claimed).    ADVANTAGE - The electroconductive ink has excellent soldering property and adhesiveness with respect to metallic substrates, and enables formation of stable and reliable electrical interconnection with excellent bonding strength.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) bonded assembly, which consists of electrically-connected primary substrate and secondary substrate. The primary substrate has one or more electroconductive pathways formed on the surface using dried product, and one or more electroconductive pathways attached to the secondary substrate using a soldering material;    (2) solar module, which consists of the bonded assembly;    (3) formation of electroconductive pathway on substrate, which involves providing the electroconductive ink, applying the electroconductive ink on one or more portions of the substrate, and exposing the substrate at a temperature of 70-300 degrees C and forming electroconductive pathway on one or more portions of the substrate;    (4) formation of bonded assembly, which involves providing the electroconductive ink, applying the electroconductive ink on one or more portions of primary metallic substrate, exposing the substrate and forming electroconductive pathway on one or more portions of the substrate, and soldering the secondary metallic substrate to the electroconductive pathway and forming an electroconductive connection between the primary and the secondary substrates; and    (5) usage of electroconductive ink, for formation of electroconductive pathway on substrate.
