Abstract: A method of manufacturing an electronic component unit comprises the steps of forming a conductive pattern on a surface of a substrate, roughening a surface of a connecting area of said conductive pattern, printing an adhesive on the connecting area, connecting an electrode of an electronic component to the electroconductive adhesive on the connecting area, and drawing the adhesive at a temperature of 50-120° C.

Abstract: An electric rotating machine as disclosed herein includes an armature core having an outer peripheral portion with slots, a rotatable shaft having an outer periphery and rotatably supporting the armature core, a plurality of lower layer coils each having at opposite ends thereof respective lower layer coil protrusion portions, and a plurality of upper layer coils disposed radially outside of the lower layer coils and each having at opposite ends thereof respective upper layer coil protrusion portions. According to the novel method of this invention, the lower layer coil protrusion portions are bonded to the upper layer coil protrusion portions with a welding torch of an arc welding machine by radially moving at least one of the welding torch and boundary portions, at which the corresponding protrusion portions abut one another, relative to each other.
