A carrier tape according to the present invention includes a plurality of tape carrier packages provided at a regular interval on a lengthy insulating tape, a first and a second integrated circuit device respectively and mounted to each of the plurality of tape carrier packages. Further, a connecting line electrically short-circuits only between one of terminals for the first integrated circuit device and one of terminals for the second integrated circuit device. This configuration prevents the integrated circuit devices from being damaged by discharged static electricity as well as allows to conduct a performance test on the integrated circuit devices such as checking for input/output of a signal by applying a probe pin to an input or output pin.
