We call it governing equation inverse problem to estimate governing equation. So far, the domain-type inverse analysis method to estimate governing equation was proposed. In the meantime, we propose the boundary-type inverse analysis method newly. It has some advantages compared to the domain-type. For example, it makes analysis easier, it need less data, etc. Therefore we consider the establishment of boundary integral-type inverse analysis method. In this study, we consider 2-dimentional potential problem and propose the method to estimate modulus of governing differential equation by the boundary integration. As a result, not only the case that coordinate axis and orthotropic anisotropy axis are corresponding but also the case not corresponding, we got quite good estimation result. Moreover, the case of boundary observed values include observed noise, we got relatively good estimation result.
