A sensing structure is provided. The sensing structure includes a first substrate, a second substrate, a sensing unit, and a flexible printed circuit (FPC). The sensing unit is disposed on the first substrate and adapted to generate a signal when the sensing unit is touched. The FPC has a first end and a second end. The first end includes a first connecting portion and a second connecting portion. The first connecting portion is disposed on the first substrate and electrically connected to the sensing unit, and the second connecting portion connects to the second substrate.
