Abstract：
The string tension of the infinite string in the lattice Schwinger model is precisely calculated with the Hamiltonian which has the solvable exact ground state. The result shows that in the lattice Schwinger model, one can obtain the linear confinement potential and no phase transition occurs when a approaches zero. This result coincides with that obtained in the continuum theory.
