1. A glasses-type electronic device comprising:
a housing;
a lens frame provided as a part of the housing;
a first wearing member extending from a first end of the lens frame;
a first printed circuit board (PCB) accommodated in the first wearing member;
a second wearing member extending from a second end of the lens frame;
a second PCB accommodated in the second wearing member; and
a flexible PCB (FPCB) extending from the first PCB through the lens frame and electrically connected to the second PCB, the FPCB being a single FPCB including a plurality of layers; and
a conductive member electrically connected to the single FPCB and disposed in the lens frame,
wherein the FPCB comprises the plurality of layers providing at least one of a power wiring line or a signal wiring line,
wherein the FPCB further comprises, a first wiring line for a first signal, which is disposed in at least one of an uppermost layer or a lowermost layer of the plurality of layers, and a second wiring line configured to transmit a second signal, which is disposed in an inner layer disposed between the uppermost layer and the lowermost layer among the plurality of layers,
wherein the first signal has a higher speed than a speed of the second signal and
wherein the conductive member is located at an upper end of the lens frame and configured to prevent at least one of a voltage drop or an infrared (IR) drop.
