Abstract
Provided is an electronic device that can prevent an increase in a temperature of an internal electronic component, and prevent a heat influence on adjacent electronic devices or the like. The electronic device includes: a circuit board on which a heat-generating element configured to generate heat is mounted; a housing in which the circuit board is housed; a heat dissipation portion connected to the housing and configured to dissipate heat; a heat transfer member disposed between the heat-generating element and the heat dissipation portion, and configured to transfer heat generated by the heat-generating element to the heat dissipation portion; and a housing cover provided on a side of the heat dissipation portion opposite to a side of the heat transfer member, in which a convection area that is a space where air convects is provided between the heat dissipation portion and the housing cover.
