We investigate the effects of r-process elements on the electromagnetic wave emission from peculiar core-collapse supernovae. We perform a series of radiative transfer simulations based on one-dimensional hydrodynamical explosion models. Varying the mass of 56Ni and r-process nuclei, we examine the effects of r-process elements on the light curves. The 56Ni-powered explosion models with a large amount of r-process-rich material show redder color because the high opacity of r-process elements suppresses the emission at shorter wavelengths. Comparing the results with the color of observed super-novae, we find that the upper limit for the production of r-process elements is 0.1M ⊙ for 56Ni-powered supernovae.
