We propose a new method for representing the path integral over gauge fields as a tensor network. We apply the tensor renormalization group with this method to three-dimensional pure 𝑆𝑈(2) gauge theory. Our result for the free energy in the weak/strong coupling regime agrees with that obtained by the weak/strong coupling expansion.
