Abstract: An electronic device having a heat dissipation function is proposed. The electronic device includes: a heating element (20); a shield can (30) covering the heating element (20) to block electromagnetic waves; and a heat dissipation means (50) provided to be adjacent to the heating element (20) and causing an ionic wind to flow into a shielded space (32) of an inner part of the shield can (30). Here, the heat dissipation means (50) includes: a wire electrode (70) provided to be adjacent to an entrance of the shielded space (32) of the shield can (30) and becoming an emitter electrode; and a power module (80) connected to the wire electrode (70) and applying voltage to the wire electrode (70), wherein the shield can (30) is grounded at the same time of being connected to the power module (80) and becomes a collector electrode.
