    摘要: A bonding apparatus has a probe (16) for causing an LED chip (14) to emit light before the LED chip (14) is bonded on a board (12), an imaging system (18) for recognizing the center of a light-emitting area of the LED chip (14) and recognizing coordinates of a contour reference point of the LED chip (14) with respect to the recognized center of the light-emitting area, and a light-emitting-element holding mechanism (20) for positioning the LED chip (14) in a bonding position on the board (12) based on the recognized coordinates of the contour reference point. The center of the light-emitting area of the LED chip (14) can be positioned highly accurately in a desired position on the board (12) without being adversely affected by variations in the contour dimensions of the LED chip (14).
