Abstract
We consider the strong-coupling phase in a model of spin-2 field theory in de Sitter spacetime and the effective mass of spin-2 fields therein. In the strong-coupling phase, the Higuchi bound limits the mass parameter in the theory. The analysis using the large approximation finds the critical value of the mass parameter with numerical calculation.
