N2 - We investigate the tensor perturbation in the inflation model driven by a massive scalar field in Eddington-inspired Born-Infeld gravity. For short-wavelength modes, the perturbation feature is very similar to that of the usual chaotic inflation. For long-wavelength modes, the perturbation exhibits a peculiar rise in the power spectrum which may leave a signature in the cosmic microwave background radiation.
