We show that the coupling constants of neutrino-scalar interaction are actually restricted to be y_i < 1.5 x 10^{-3} by supernova neutrino observation, and further constrained to be y_i < 2.3 x 10^{-4} by precision measurements of acoustic peaks of the cosmic microwave background. Based on the energy-loss argument for supernova cores, we derive a slightly more restrictive bound y_i < 3.5 x 10^{-5}.
