Claim:
An aerator comprising: a ventilating member that is disposed opposedly to a heat generating object, and that allows air to flow through an inside; and an inlet device that takes in air from an outside, and that sends the air to the ventilating member, the ventilating member including: a discharging portion that discharges the air flowing through the ventilating member to the outside; an opening through which heat generated by the heat generating object is taken in the ventilating member; and a restraining portion that restrains the air taken in by the inlet device from flowing to the heat generating object through the opening, wherein the restraining portion comprises a dividing portion that divides an interior of the ventilating member into a first ventilating path and a second ventilating path, wherein the air taken in by the inlet device is divided by the dividing portion such that more of the air taken in by the inlet device flows through the first ventilating path than the second ventilating path, and wherein the opening is disposed in the second ventilating path.
