We report on the recent result according to which the non‐perturbative vacuum structure associated with neutrino mixing leads to a non‐vanishing contribution to the value of the cosmological constant. Its value is estimated by using the natural cut‐off appearing in the quantum field theory formalism for neutrino mixing.
