The integral transformations have become very important in solving differential equations, especially those that have an applied aspect in the physical, chemical, economic and other scientific fields. In this article, the suggested transform which named by SEJI integral transform is developed for solving the partial derivatives and applied to solve several partial differential equations.  This paper introduced the definition of the suggested transform with its properties that have the importance in this field. This new transform has an ability to applying in {PDEs) and finding the exact solution for these equations. Kinds of partial differential equations have solved by using this transform.
