In numerical calculation with a digital computer, one must often consider problems of interpolation between given data points. One of such interpolating functions is known as a spline function. A spline function has already between applied not only to interpolating problem, but also to the method of solving a ordinary differential equation. In this paper, furthermore, we try to apply the spline function to a numerical bouble integration. Especially, it is interesting to be able to obtain the formula for the case in which a integrand is composed of a product of three functions. This integration is common in the field of physics. Here, the spline functions and the integration formula are expressed by matrices.
