The invention discloses a laterally-distributed six-sensitive-grid full-bridge metal foil gauge capable of measurement of double-side outer lateral partial derivatives. The metal foil gauge comprises a substrate and six sensitive grids fixed thereon; each sensitive grid comprises a sensitive segment and a transition segment, and axes of the sensitive segments are parallel lines in the same plane; in the plane, the direction along the direction of the axes is an axial direction, and the direction vertical to the axial direction is a lateral direction; centers of the six sensitive grids are not axially deviated yet laterally deviated; the sensitive grids are an upper seventh sensitive grid, an upper fifth sensitive grid, an intermediate upper sensitive grid, an intermediate lower sensitive grid, a lower fifth sensitive grid and a lower seventh sensitive grid from the left to the right along the lateral direction according to a sequence of center positions of the sensitive grids; and total resistance change values of the six sensitive grids under the same strain are 7:5:12:12:5:7. According to the invention, lateral first-order partial derivatives of positions where the intervals between the centers of the upper seventh sensitive grid and the lower seventh sensitive grid and the centers are equal to the intervals between the centers to the centers of the lower fifth sensitive grid and the upper fifth sensitive grid can almost be measured at the same time.
