Summary:PROBLEM TO BE SOLVED: To provide an electronic device including a forced-cooling cooler disposed adjacent to a ventilation port, capable of improving cooling efficiency and reducing a temperature rise within a housing by reducing a circulating current into the housing of heat-received cooling air. SOLUTION: The electronic device comprises the housing having a side wall including the ventilation port, a heating element stored in the housing, a radiator disposed adjacent to the ventilation port, a fan disposed adjacent to the radiator to generate cooling water toward the radiator, and a blocking member for blocking a clearance between the radiator and the side wall having the ventilation port. A cutout for avoiding a mechanical interference with a heat pipe is provided on a side blocking plate of the blocking member, and the side blocking plate is integrally formed in a rib structure by connecting an edge thereof to at least one of a bottom wall of the housing and the side wall having the ventilation port.
