ABSTRACT:
A light-shielding aluminum nitride sintered body essentially consists of aluminum nitride crystal grains and 0.01 to 1.5 wt % (an element content in the case of a transition metal compound) of homogeneously dispersed transition metal particles and/or transition metal compound particles having an average particle size of 5 .mu.m or less and has a thermal conductivity of 200 W/m.K or more.
