Abstract
We compute the Wald entropy of the Schwarzschild black hole in the ghost-free, infinite-derivative gravity that is quadratic in curvature. This is not given purely by the area law but includes an additional contribution depending on the power of the d’Alembertian operator, when requiring that the massless graviton be the only propagating mode in the Minkowski spacetime.
