The integrated Sachs-Wolfe (ISW) effect is an important implication for dark energy. In this paper, we have calculated the power spectrum of the ISW effect in the time varying vacuum cosmological model, where the model parameter $\ensuremath{\beta}=4.407$ is obtained by the observational constraint of the growth rate. It is found that the source of the ISW effect is not only affected by the different evolutions of the Hubble function $H(a)$ and the dimensionless matter density ${\ensuremath{\Omega}}_{m}(a)$, but also by the different growth function ${D}_{+}(a)$, all of which are changed due to the presence of a matter production term in the time varying vacuum model. However, the difference of the ISW effect in the $\ensuremath{\Lambda}(t)\mathrm{CDM}$ model and the $\ensuremath{\Lambda}\mathrm{CDM}$ model is lessened to a certain extent because of the integration from the time of last scattering to the present. It is implied that the observations of the galaxies with high redshift are required to distinguish the two models.
