To solve the problem that electric power is ununiformly generated, the power generation amount is unstable, the location is affected by the quality of installation conditions, and a large area is needed for the installation in a conventional wind power generation because the electric power generation is performed using natural wind.

A compact-sized wind power generation type air power device obtains wind power using air flow that has always stable speed and a reduced wind receiving area by artificially making wind from air instead of natural wind, generates the stable power generation amount, and can be installed indoors.
