Provided is a suspending body tension measuring device for an elevator, configured so that errors included in a measurement result can be reduced. A suspending body tension measuring device 6 for an elevator is provided with: a camera 601 which is provided to an elevator car 2 supported by the rope 1 of the elevator, and which captures an image of the rope 1; a waveform extracting unit 602 which extracts the waveform of vibration of the rope 1 using the image captured by the camera 601; an analysis unit 603 which calculates the vibration frequency of the rope 1 using the extracted vibration waveform; an acceleration sensor 604 which measures acceleration acting on the camera 601; and a determination unit 605 which, using the measurement result obtained by the acceleration sensor 604, determines whether or not the acceleration acting on the camera 601 exceeds a predetermined range.
