Abstract
A heat dissipation member includes a condensation area, an evaporation area, and a capillary structure layer. The condensation area is arranged away from a heating element of an electronic apparatus in an application state. The evaporation area is arranged close to the heating element in the application state. A capillary force of the capillary structure layer in the evaporation area is greater than a capillary force of the capillary structure layer in the condensation area.
