Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a vehicular display device, which has a heat generating component 10 installed in a case 17 and can restrict an increasing in temperature of the heat generating component 10 by discharging heat generated at the heat generating component 10 out of the case 17 in a superior manner. SOLUTION: A speaker 21 is disposed near a power supply IC 10 and at the same time the speaker 21 is operated under such a low frequency as one that is not audible to human ears except an occasion that audio information is outputted through the speaker 21, and air kept in the case 17 is moved through vibration of the speaker 21. With this arrangement, the speaker 21 compresses the air in the case 17, expands and vibrates it to cause the air around the power supply IC 10 to be moved and enables a temperature of the power supply IC 10 to be decreased.
