PROBLEM TO BE SOLVED: To provide a casing structure of audio equipment in which temperature rise in a disk player is effectively suppressed by heat radiation through natural convection. SOLUTION: In the audio equipment, a power IC (a heat generating element) 1 is mounted on a heat sink 2 on one side section of a casing 5 which stores and holds a disk player 3 and a top section ventilation port 6 and a bottom section ventilation port 7 are provided to form ascending current of air. Furthermore, in order to take in external air from other side section of the casing 5 and guide toward the ascending current of air, a side section ventilation port 9 is provided to the portion facing the other side section of the casing 5 (a side plate section of an opposite heat sink 2 side approximately facing the power IC 1, for example).
