To provide a lens-fitted photographic film unit whose cost is reduced by easily lowering the color temperature of stroboscopic light passing through a stroboscopic panel without mixing a material of the stroboscopic panel with a dye or coloring a xenon tube.

In the lens-fitted photographic film unit with a built-in simple photographing mechanism and a preliminarily loaded unexposed photographic film, a part or the whole of an outer packing member which coats the photographing mechanism and a stroboscopic panel which transmits and irradiates at least stroboscopic light are coated with a shrink film, and part of the shrink film facing to the stroboscopic panel is colored so that the color temperature of stroboscopic light is lowered.
