Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a vertical displacement meter of simplified structure capable of achieving cost reduction while precisely measuring a vertical displacement without being affected by external factors. SOLUTION: The vertical displacement meter is provided with an optical fiber 9a, a float 6a drifting on a fluid level of a liquid tank for detection 3a to vertically move depending on liquid level variation of the liquid tank for detection 3a, and a wire 7a connecting one end of the optical fiber 9a with the float 6a and transmitting a momentum caused by the movement of the float 6a to the optical fiber 9a to generate a strain due to the momentum on the optical fiber 9a.
