A noise insulation structure of a vehicle frame comprises a side sill, a pillar reinforcement having a lower-end portion joined to the side sill and a closed-cross section, a vertical wall portion extending upward from an upper-face portion of the side sill, and a noise insulating plate provided to be separated upward from the upper-face portion of the side sill and forming a space portion extending in a vertical direction together with the upper-face portion, the vertical wall portion, and the pillar reinforcement. An opening portion is formed at an inside portion of the upper-face portion which is positioned inside the space portion such that it penetrates the upper-face portion. An opening ratio of an opening area of the opening portion to an area of the inside portion of the upper-face portion is set to be 0.2 or less.
