Abstract
A portable device includes a first casing which houses a circuit board having a first conductive layer, a second casing which houses a circuit board having a second conductive layer, and a coupling part which openably and closably couples the first casing and the second casing. The coupling part is made of a metal material, and the first conductive layer is electrically connected to the second conductive layer via the coupling part.
Claims9
A portable device comprising:
- a first casing which houses a circuit board having a first conductive layer;
