摘要：
A spectral distribution measuring device includes an illumination unit (13) configured to illuminate white light to a surface of an object (12) being measured; a slit array (15) having a plurality of slits formed in alignment at equal intervals; a linear image sensor (18) including a light receiving face (18b) having a plurality of rectangular pixels (19) adjacently arranged in alignment and a plurality of spectral light-irradiated areas divided in each predetermined number of neighboring pixels; a plurality of areas being measured which is set on the surface of the object being measured, and reflects the light irradiated by the illumination unit to the plurality of slits; and a diffraction unit (17) configured to diffract and disperse reflection light which is reflected from the areas being measured and has passed through each slit, the diffraction unit being disposed such that a direction where a diffraction image expands is inclined at an angle to a direction where the light receiving face expands.
