<p>A TCP testing method for testing TCPs (31) in sequence is provided with a test step (S32) wherein a carrier tape (30) is transferred in a forward direction from a supplying reel (21) to a take-up reel (22) and the TCPs (31) are tested in sequence; and a punching step (S42) wherein the carrier tape (30) is transferred in a backward direction from the take-up reel (22) to the supplying reel (21) and the TCPs (31) on the carrier tape (30) are punched based on the results of a prescribed test.</p>
