A method of removing a binder from a green body capable of accomplishing the binder removal at a substantially reduced temperature and in a significantly reduced period of time. The binder mainly consists of a polymer material of ultraviolet degradation properties such as, for example, a polymer material having a main chain containing a tertiary carbon atom. The green body is irradiated with ultraviolet rays at a temperature within the range of 150.degree. C. to 300.degree. C. under an atmospheric pressure to rapidly carry out the photo degradation of the polymer material by ultraviolet rays, so that the binder may be readily removed from the green body.
