Abstract
A spectroscopic measurement device capable of preventing entry of stray light into an optical fiber and preventing a decrease in accuracy of data of a spectrum of light incident on the optical fiber. The spectroscopic measurement device includes a light source unit, and a light detection unit in which transmission light transmitted through the article is incident on an optical fiber and a spectral characteristic of the transmission light passing through the optical fiber is measured by the spectroscope, in which the light detection unit further includes a tubular member between the article and the optical fiber, and an opening on an end of the tubular member on a side facing toward the article is positioned on the article side with respect to an incidence end of the optical fiber and the transmission light passes through the tubular member from the opening and is incident on the optical fiber.
