Abstract
A wind velocity measuring device is used in an electronic apparatus including cooled objects and cooling fans for cooling the cooled objects and measures a wind velocity of air blown to the cooled objects. The wind velocity measuring device includes a wind velocity measuring unit that measures a wind velocity of air, and an air circulating unit that circulates a portion of the air blown to the cooled objects. The air circulating unit includes barrier portions that extend to cross a circulation direction of the air at a front stage side of the circulation direction of the air, and an exhaust port that discharges inner air to the outside and is formed at a rear stage side of the circulating direction of the air, and the wind velocity measuring unit measures a wind velocity of the air between the barrier portions and the exhaust port in the air circulating unit.
