PROBLEM TO BE SOLVED: To provide a spectrophotometric device that enables accurate photometry by suppressing internal reflection on a surface not including a function to guide light to an inspection target surface of a light guide body having an illumination optical system and a light guide optical system integrated as one body to reduce stray light on a light receiving element.SOLUTION: A spectrophotometric device includes a housing 401 that has a lateral surface 401e that is an opposing surface arranged at a position opposite to a lateral surface 403e that is at least one surface of adjacent surfaces adjacent to an incident surface 403a of a light guide body 403 on which illumination light 202a from a light source 202 is made incident; the lateral surface 403e and the lateral surface 401e are closely bonded to each other with a resin-made adhesive 450.SELECTED DRAWING: Figure 8 |
