    • A fuel supply apparatus for an internal combustion engine includes: a feed pump (22) capable of feeding a fuel of the internal combustion engine; a high pressure fuel pump (31) that pressurizes the fuel fed from the feed pump (22); and a second injector (37 A, 37B) that supplies the pressurized high-pressure fuel to the internal combustion engine selectively. An ECU (50) of the fuel supply apparatus includes: a pulsation width detection unit (101) that detects a pulsation width in a pressure of the fuel fed from the feed pump (22) to the high pressure fuel pump (31); and a feeding condition determination unit (102) that determines that a condition variation causing fuel vapor to form in the fuel fed to the high pressure fuel pump (31) has occurred when the pulsation width detected by the pulsation width detection unit (101) falls rapidly to a preset threshold variation width.

    • The laminated diffractive optical element includes plural diffraction gratings 21, 22 and 23 laminated with each other, the respective diffraction gratings being formed of a same light-transmissive material. In the element, reflective films are formed on grating surfaces 11 and 12 of the respective diffraction gratings, each of the reflective films being disposed between the diffraction gratings. Each of the reflective films reflects light in a specific wavelength range and transmits light in a wavelength range different from the specific wavelength range, the specific wavelength ranges of the respective reflective films being different from each other. The grating surfaces of the respective diffraction gratings are formed in shapes different from each other according to the specific wavelength ranges corresponding to the respective reflective films.
