In an electronic chip supplying apparatus, a vacuum suction device for sucking a retainer tape which encases electronic chips is provided in a retainer tape support member provided at an opening position where the electronic chips are picked up from a chip pickup device, or a tension applying device for the retainer is provided. Thus, vertical fluctuation of the retainer tape is prevented at the opening position.
