Electronic device including at least one light source and heat dissipation structure

An electronic device comprising:

• a cover including a first surface which is a portion of an outer surface of the electronic device and a second surface facing in a direction opposite to the first surface, and including a light transmission portion;
• a substrate disposed in an inner space of the electronic device;
• a light source disposed on the substrate to emit flash light through the light transmission portion;
• and
• a light reflection member disposed on the second surface of the cover to surround at least a portion of the light transmission portion,
• wherein the light reflection member is configured to reflect a portion of the flash light, emitted by the light source, in a direction toward the inner space from the cover.
