* Abstract : We conjecture that there is a universal relation between the ground state glueball mass and the string tension in confining gauge theories, as a direct consequence of monopole condensation for the confinement. We support our conjecture with numerical evidences from the lattice data and also from arguments, based on the Bethe-Salpeter analysis, scale anomaly, and QCD sum rules.
