A LOW COST IC TRANSPORTING APPARATUS LOCATES A SEMICONDUCTOR DEVICE AT AN ACCURATE POSITION, PICKS UP THE SEMICONDUCTOR DEVICE BY SUCTION, AND TRANSPORTS THE SEMICONDUCTOR DEVICE. A PLAY IS PROVIDED IN A POSITIONING RECESSED PORTION (5, 31) HAVING UPWARDLY INCLINED SURFACES SO THAT A SEMICONDUCTOR DEVICE FALLEN INTO THE POSITIONING RECESSED PORTION CAN MOVE IN A HORIZONTAL DIRECTION. A GUIDE (16,34) SURROUNDS A DEVICE SUCTION UNIT (15, 33) PICKING UP BY SUCTION THE SEMICONDUCTOR DEVICE FALLEN INTO THE POSITIONING RECESSED PORTION. THE GUIDE GUIDES THE DEVICE SUCTION UNIT TO PICK UP BY SUCTION THE SEMICONDUCTOR DEVICE AT A PREDETERMINED SUCTION POSITION. DOWNWARDLY PROJECTED RIDGED PORTIONS (16C) ARE PROVIDED ON THE LOWER END OF THE GUIDE, EACH OF WHICH INCLUDES A SHAPE (16D) CONFORMING TO A CORRESPONDING ONE OF THE UPWARDLY INCLINED SURFACES OF THE POSITIONING RECESSED PORTION (5, 31). THE GUIDE ALSO INCLUDES FLAT PORTIONS (16A, 34A) PROVIDED AT THE BASE PORTION OF THE RIDGED PORTIONS THEREOF. THE FLAT PORTIONS (16A, 34A) ABUT AGAINST AN UPPER END SURFACE (4A, 31A) OF THE POSITIONING RECESSED PORTION WHEN THE RIDGED PORTIONS (16C) OF THE GUIDE ENGAGE WITH THE UPWARDLY INCLINED SURFACES OF THE POSITIONING RECESSED PORTION WITHOUT ANY PLAY THEREBETWEEN.
