When silver oxide is reduced to silver, a large number of cores of metallic silver are formed inside the silver oxide. Then, the silver oxide is reduced in a manner of being hollowed out while its original outer configuration is being maintained. As a result, the curvature of the silver generated becomes larger. The utilization of this microscopic-particle implementation mechanism allows accomplishment of the bonding even if the silver oxide is supplied not in a particle-like configuration, but in a closely-packed layer-like configuration. In the present invention, there is provided an electronic member including an electrode for inputting/outputting an electrical signal, or a connection terminal for establishing a connection with the electrical signal, wherein the uppermost surface of the electrode or the connection terminal is a silver-oxide layer.
