The first flexible substrate includes a first organic material layer, a first copper foil layer, and a first capillary structure layer. The second flexible substrate includes a second organic material layer, a second copper foil layer, and a second capillary structure layer. The first copper foil layer, the first capillary structure layer, the spacer, the second copper foil layer, and the second capillary structure layer are retracted by a distance relative to the first and second organic material layers to form a space. The first and second organic material layers and the flexible sealing member define a sealed chamber.
