Abstract: Using the twist deformation of $Uigl4,R$, the linear part of thediffeomorphism, we define a scalar function and construct a free scalar fieldtheory in four-dimensional $\kappa$-Minkowski spacetime. The action in momentumspace turns out to differ only in integration measure from the commutativetheory.
