Base member, electronic device, and structure

A base member that is a molded part on which pattern wiring is directly formed, the base member comprising

• a projection projecting from a base surface of the base member,
• wherein the pattern wiring is laid over a top of the projection,
• wherein protrusions are molded on both sides of an area at the top of the projection where the pattern wiring passes, and
• wherein opposed surfaces of adjoining ones of the protrusions are provided with pattern wiring electrically connected to the pattern wiring adjoining the protrusions.

A structure, comprising:

• a first wiring part including a first base member that is a molded part and on which pattern wiring is directly formed;
• and
• a second wiring part including a second base member that is a molded part and on which pattern wiring is directly formed,
• the first and second wiring parts which are electrically connected,
• wherein a recess is molded in the first wiring part,
• wherein a projection having a shape corresponding to the recess is molded on the second wiring part,
• wherein a first electrode is directly formed on a bottom surface of the recess by the pattern wiring, and a second electrode is directly formed on a top surface of the projection by the pattern wiring, and
• wherein electrical connection is established by the first and second electrodes contacting each other,
• wherein the first wiring part includes a latching portion,
• wherein the second wiring part includes a portion to be latched,
• wherein the first and second wiring parts are mechanically fixed to each other by the latching portion latching with the portion to be latched, and
• wherein electrical connection is established by pattern wiring formed on the latching portion and pattern wiring formed on the portion to be latched contacting each other.
