Abstract: A heat-dissipating structure is formed by bonding a first member and a second member, each being any of a metal, ceramic, and semiconductor, via a die bonding member; or a semiconductor module formed by bonding a semiconductor chip, a metal wire, a ceramic insulating substrate, and a heat-dissipating base substrate including metal, with a die bonding member interposed between each. At least one of the die bonding members includes a lead-free low-melting-point glass composition and metal particles. The lead-free low-melting-point glass composition accounts for 78 mol % or more in terms of the total of the oxides V2O5, TeO2, and Ag2O serving as main ingredients. The content of each of TeO2 and Ag2O is 1 to 2 times the content of V2O5, and at least one of BaO, WO3, and P2O5 is included as accessory ingredients, and at least one of Y2O3, La2O3, and Al2O3 is included as additional ingredients.

Abstract: Disclosed herein is a method for producing an electrode includes a step of reducing lithium-vanadium oxide by heating in reducing gas, a step of causing the reduced lithium-vanadium oxide to deliquesce, a step of mixing the deliquesced lithium oxide with an active material so as to prepare an electrode mixture, and a step of making the electrode mixture into an electrode by virtue of molding after heat treatment to the electrode mixture. The method for producing an all-solid battery further includes a step of bonding the thus-made electrode to a solid electrode layer in such a way that the solid electrode layer is interposed between the electrode and either of cathode and anode to be paired with the electrode.
