Abstract:
1. An electronic device comprising: an electronic component; a joining member to be mechanically joined with the electronic component; a metal conductor arranged between the electronic component and the joining member to mechanically join the electronic component and the joining member, wherein: the metal conductor is made of porous noble metal to have pores, the metal conductor includes an end surface uncovered by the electronic component and the joining member, and in a cross section of the metal conductor, the metal conductor before resin impregnation has: a mold resin configured to seal the electronic component, the joining member and the end surface of the metal conductor; a primer arranged at least between the end surface of the metal conductor and the mold resin to increase an adhesiveness therebetween; and a reinforcing resin impregnated from the end surface of the metal conductor to an inside of the metal conductor, to mechanically reinforce the metal conductor, wherein the primer and the reinforcing resin are made of a same resin material, and the reinforcing resin has a higher adhesion strength with the primer than the metal conductor.
