A color filter for acquiring information of specific wavelength regions, a kit, a color filter manufacturing method and an optical sensor are provided. This laminate color filter comprises at least one absorptive color filter and at least one reflective color filter. The absorptive color filter and the reflective color filter are stacked on top of each other. Defining n as the number of types of wavelength regions of the absorptive color filter, n as the number of types of wavelength regions of the reflective color filter, and p as the number of types of wavelength regions of the laminate color filter, is holds that p > m ≧ 2 and p > n ≧ 2.
