PROBLEM TO BE SOLVED: To provide a ventilation device capable of improving efficiency of a heat exchanging element composed of a layered body. SOLUTION: In this total enthalpy heat exchange type ventilation device, a chamber is disposed between a wind approach face of the total enthalpy heat exchanging element composed of the layered body and an air inlet formed on a device housing-side wall, and a straightening lattice and a straightening plate are disposed at a front part of the approach face in the chamber to unify the wind volume and wind velocity of the wind passing through the total enthalpy heat exchanging element by each layer of the layered body to improve heat exchanging performance. Thus the device can be miniaturized, and energy-saving in ventilation of each room of a house and the like can be promoted. As the wind approach face of the heat exchanging element is roughly square, and its area is much bigger than the circular air inlet, the intake air can be dispersed and unified.
