PURPOSE: A mobile electronic device is provided to suppress temperature rise in the surface of the mobile electronic device caused by heat from a heat source. CONSTITUTION: A mobile electronic device comprises: a first casing(10a); a second casing(10b) disposed opposed to one of surfaces of the first casing and capable of changing a position relative to the first casing while maintaining a state where opposed surfaces are opposed; and a heat source disposed in the second casing. A surface of the second casing includes: a first region which is covered with the first casing in a first state where the first and the second casings are opposed and is exposed to the outside in a second state where the position relative to the first casing is changed and area of the opposed surfaces of the first and the second casings decreases from the first state; and a second region which is always exposed to the outside in both of the first and the second states. At least a part of the heat source is disposed in a position corresponding to the first region. |
