Abstract
A chip component conveyor belt of the present invention comprises an endless timing belt having a plurality of teeth at predetermined intervals on its back surface. Wherein a height of the teeth is made uniform by polishing or grinding the tip of each tooth. Thus, there arises no variation of surface height of the endless timing belt even when any tooth of the endless timing belt meshes a timing pulley, or even when the endless timing belt is supported by a belt guide member.
