According to one embodiment, a pulse wave velocity measuring device includes a first sensor, a second sensor, a base body and a calculation unit. The first sensor is configured to sense a pulse wave propagating through an interior of a vessel. The second sensor is separated from the first sensor and is configured to sense the pulse wave. The base body is configured to hold the first sensor and the second sensor and regulate a distance between the first sensor and the second sensor. The calculation unit is configured to derive a difference between a time of the sensing of the pulse wave by the first sensor and a time of the sensing of the pulse wave by the second sensor.
