A biological body inspection apparatus includes a measurement module that acquires an amount of light having a wavelength under measurement contained in light incident on the measurement module and an enclosure that accommodates the measurement module and has a window that transmits light traveling toward the measurement module. An adhesive member is provided on a surface of the enclosure at least in an area thereof that surrounds the window. The adhesive member has a light blocking section that is located in an area outside the window and surrounds the window in a plan view in the direction along the optical axis of the light traveling toward the measurement module and blocks light that belongs to a measurement wavelength region within which at least the wavelength under measurement is present.
