It is shown that the reheating temperature of the Universe can be determined observationally by future space-based laser interferometer experiments such as DECIGO and/or BBO if it is around 10{sup 6-9} GeV, depending on the tensor-to-scalar ratio r. As an application, it may provide an evidence of the gravitino dark matter scenario, if it is the LSP.
