To provide a method and a device for recognizing an electronic part by which, even when the suction position of a nozzle is photographed while it is out of the center of a chip, the chip can be recognized accurately in an electronic part mounting device for mounting electronic parts on an electronic circuit board.

The electronic part mounting device is provided with a lower lighting fitting 25 and a side lighting fitting 27 in addition to coaxial lighting fitting 23 to direct light while changing an angle of lighting, and it also determines based on image recognition processing whether or not the lower surface of the nozzle is photographed, and a projecting area from the chip sucked to the nozzle is reduced without giving an influence to the image recognition processing, and then the photographed image is picked up to generate image recognition data through the image recognition processing.
