A cassette for receiving a circuit board is provided to make a cassette efficient in storing and transporting a circuit board by providing stable combination structure of crossbar supporting the boards on each floor directly. A cassette for receiving a circuit board comprises: an upper and a lower plate; the first and the second lateral side frame bars(132a,132b,132c,132d,132e,132f) which link both ends of the upper and the lower plate facing each other; backside frame bars(132g,132h) which link one side edge of the upper and the lower plate; multiple crossbars(140) which link the first and the second lateral side plates and are connected to the first and the second lateral side frame bar through bolts and have the first washers with saw tooth shaped spiral ridge on their one side, each of which is divided into a linkage part linked with the first or the second lateral side frame bar and a support part supporting a circuit board(110) directly.
