PROBLEM TO BE SOLVED: To provide a paper carrier tape manufacturing method in which a chip accommodation recess is formed with excellent accuracy, a part of a bottom part of the chip accommodation recess has appropriate strength against protrusion of a push-out pin, and the chip accommodation recess is machined so as not to have any hole in the bottom part thereof. SOLUTION: In a first step, a through hole 2 is made in a paper carrier tape base material 1a, in a second step, a punch 5 is pressed against the through hole 2 to form the chip accommodation recess 3 over the through hole 2 in the paper carrier tape base material 1a, and the through hole 2 is closed by a part of the paper carrier tape base material 1a. Thus, the paper carrier tape 1 is manufactured. Since the paper carrier tape 1 is manufactured via the first and second steps, the chip accommodation recess 3 is formed with excellent accuracy, and no hole is made in the bottom part of the chip accommodation recess 3, but it is easily opened.
