  We study the Abelian and non-Abelian action densitynear the monopole in the
maximal Abelian gauge of SU(2) lattice gauge theory. We find that the
non-Abelian action density near the monopoles belonging to the percolating
cluster decreases when we approach the monopole center. Our estimate of the
monopole radius is R_mon ~ 0.04 fm.
