PROBLEM TO BE SOLVED: To provide a portable fan combining practicability and amusement by providing a display function using the afterimage effect of eyes. SOLUTION: A luminescent member is disposed at a blade or a blade support member. The operating state of the luminescent member is controlled by current application, and the blades are rotated to display a pattern and an image on the moving locus of the luminescent member, using the afterimage effect of eyes. The portable fan is thereby provided for enjoying the pattern and image while feeling cool during watching a game of sports at night or using the fan indoors with slight illumination.
