Abstract
An electromagnetic induction panel structure includes a multilayer substrate, a first cover unit and a second cover unit. The multilayer substrate includes a first outermost lateral conductive layer and a second outermost lateral conductive layer respectively disposed on two opposite outermost surfaces thereof. The first cover unit is disposed on the first outermost lateral conductive layer. The second cover unit is disposed on the second outermost lateral conductive layer. For example, the first cover unit includes a first insulating layer directly formed on the first outermost lateral conductive layer for directly contacting the first outermost lateral conductive layer. The second cover unit includes a second insulating layer directly formed on the second outermost lateral conductive layer for directly contacting the second outermost lateral conductive layer. The second cover unit includes a wave-absorbing material layer directly formed on the second insulating layer for directly contacting the second insulating layer.
