This temperature measurement device is provided with: a detector that detects a first Stokes component and a first anti-Stokes component in back-scattered light produced when light enters a first end of an optical fiber, and detects a second Stokes component and a second anti-Stokes component in back-scattered light produced when light enters a second end of the optical fiber; a correction unit that, within a prescribed region containing a sample point of a partial region of the first end side of the optical fiber, calculates a first segment in accordance with a first correlation, of the second Stokes component to the first Stokes component and the first anti-Stokes component, calculates a second segment in accordance with a second correlation, of the second anti-Stokes component to the first Stokes component and the first anti-Stokes component, smooths the second Stokes component in the first segment, and smooths the second anti-Stokes component in the second segment; and a measurement unit that measures a temperature using the smoothed second Stokes component, the smoothed second anti-Stokes component, the first Stokes component, and the second Stokes component. |
