To provide a satchel for school children capable of being easily distinguished from the satchels for school children of other children without attaching a name plate and prevent a traffic accident by improving the visibility.

A satchel for school children 10, in which a plurality of three-dimensional projections 14 comprising polyhedrons and having light reflectivity are fixed on an outer surface 11a of the satchel for school children 10 with a predetermined interval apart from each other and three-dimensional sticking members 15 having a recess section in the back and translucency are attached, can be easily distinguished from the satchels for school children 10 of other children by sticking the sticking member 15 on the projection 14 at an arbitrary position so as to fit the projection 14 to the recess section, and can attract attention of drivers of cars, motorcycles, or the like by diffusely reflecting external light due to the three-dimensional projection shape. The projection 14 catches on the recess section and separation is hard to occur.
