In this paper, we focus on the adaptive boundary element method (ABEM) of Laplace problem in exterior sector domain. The property of natural integral operator and the integral kernel series expansion method lead to the reliability a posteriori error estimates. Some numerical experiments conclude the paper with empirical evidence of the superiority of the ABEM.
