A manufacturing method for an electronic component forms with a high degree of accuracy a portion of an outer electrode on a main surface of a dielectric block. The etching stopper film is a film formed by depositing at least two films, made of constituent materials identical in quality to each other, one another. A user sends data to be encrypted to a trusted EWS, along with authorization information. The first resister and the second resister are each arranged substantially symmetrically relative to the path. The extending part further covers the trace line area, and connects to the surface of the substrate using a fixing material. A method of manufacturing the flexible circuit compression connector system that includes a compression assembly by forming the contacts into a preselected configuration and securing the contacts to the flexible substrate is also included.
