To check the validity of the theory of nonextensive statistical
mechanics, we have investigated the nonextensive degree of the solar
interior and have tried to find the experimental evidence by
helioseismological measurements that q is different from unity. We
are able to derive a parameter for providing a lower limit to the
nonextensive degree inside the Sun that can be uniquely determined
by the solar sound speeds measured by helioseismology. After
calculating the parameter by using the solar sound speeds, we get
the lower limit of 
for all solar radii between
and 
and 
for the out
layers, 
.
Thus, the result that the nonextensive parameter q is significantly
different from unity has received the support by the experiment measurements
in helioseismology.
