Title: ELECTRONIC APPARATUS EQUIPPED WITH STRETCHABLE TRANSMISSION LINE AND METHOD FOR MANUFACTURING SAME
Abstract:
This electronic apparatus equipped with a stretchable transmission line is characterized in that: the stretchable transmission line, in which at least one resin-coated conductive wire is wound around a core comprising a water-impermeable elastic body, is inserted through a transmission line extraction hole provided in a casing of the electronic apparatus and is connected to an inner circuit; the gap between the stretchable transmission line and the transmission line extraction hole is cut off from water by a resin water cut-off body; and when the stretchable transmission line, one end of which is in the water cut-off portion and the other end of which is outside of the water cut-off portion, is stretched to 0.5 times the initial elongation at break, the outer diameter change rate of the core in the water cut-off portion is within ±5%.
