Abstract. We prove the Hyers-Ulam stability of a partial differential equation. That is, if $u$ is an approximate solution of the heat-conduction equation $\frac{\partial u}{\partial t}=a^2 \frac{\partial ^2 u}{\partial x^2}+f(x,t)$ and $\frac{\partial u}{\partial t}= a^2(\frac{\partial ^2 u}{\partial x^2}+\frac{\partial ^2 u}{\partial y^2})+f(x,y,t)$, then there exists an exact solution of the differential equation near to $u$.
