Patent ID: 7826223

Claim:
An electronic apparatus comprising: a housing that includes two surfaces extending in parallel with each other, and a side surface connecting peripheral edges of the two surfaces to each other; a circuit board that is placed in the housing and extends in parallel with the two surfaces; a plate member that extends to face a first surface of the circuit board; and a fan that is provided on a second surface of the circuit board, wherein the circuit board has a heat-generating electronic component mounted on the first surface and an opening through which air on the first surface flows to the second surface, and the plate member includes: a concave groove formed in a first surface facing a side opposed to the circuit board; a convex line formed on a second surface facing the circuit board on a portion corresponding to a back surface of the concave groove; and a guiding inclined surface formed on the back of the convex line to guide air on the first surface of the circuit board to the opening.
