To improve clear feeling and light-weight feeling, improve a view, and prevent theft during traveling by constituting a shell part of a transparent synthetic resin, providing the top part of the shell part with transparency, and processing the bottom of the shell part in such a way as hindering its transparency.

A basket 10 for a bicycle is integrally formed of colorless and transparent synthetic resin and the bottom part of a shell part 18, namely the bottom parts of the front wall 15, the rear wall, and a pair of the left/right side walls are formed into a lattice state having a plurality of vertical line parts 27 and a lot of lateral line parts 28. This constitution allows a light incident on the bottom part of the part 18 to be refracted or reflected complicatedly a light so as to hinder the transparency in the bottom of the part 18. The basket 10 for the bicycle is thus transparent so that there is nothing to hinder a view and the transparency in the bottom of the part 18 is hindered so that, when a purse or a bag is stored therein, it can be hardly recognized from the outside, thereby reducing the risk of theft.
