PROBLEM TO BE SOLVED: To provide a yarn breakage detector in a thickness direction yarn-inserting device, which can separately detect the yarn breakage and loop slippage of a thickness direction yarn by a dropper style yarn breakage detection method. SOLUTION: The yarn breakage detector 14 is disposed between a thickness direction yarn-inserting portion 11 equipped with several thickness direction yarn-inserting needles 15 disposed in a state capable of being simultaneously reciprocated to simultaneously insert several thickness direction yarns z, and a thickness direction yarn supply portion 12 for supplying thickness direction yarns z into the thickness direction yarn-inserting portion 11. The yarn breakage detector 14 has droppers hung from thickness direction yarns z in a range of from the thickness direction yarn supply portion 12 to the thickness direction yarn-inserting needles 15, and a detection portion capable of detecting which of the breakage, loop slippage and normal state of the thickness direction yarns z is the state thereof on the basis of the position of the droppers at a time when the thickness direction yarn-inserting needles 15 retreat.
