Abstract: A substrate, for example, a display glass substrate, can be transported and stored with high efficiency, without breaking and adhering dust. A substrate accommodating tray includes a frame member 12 formed to have a larger rectangular frame shape than a glass substrate and four support members 11, having elasticity, formed in an inside region surrounded by the frame member 12. The frame member 12 is formed with a pair of longitudinal direction frames 12a and a pair of width direction frames 12b, and the four support members 11 are arranged while being engaged with the frame member 12. Each support member 11 includes conductive polyethylene foam, which is molded by coating conductive particles on synthetic resin beads as a raw material and foaming it in this state. Therefore, transferring of the resin onto the glass substrate can be prevented during transportation and storage.
