Title: Method of manufacturing advanced grid structure, advanced grid structure, and space telescope using advanced grid structure

Abstract: Provided is an advanced grid structure manufactured by a lamination step of laminating a first tape prepreg group, a second tape prepreg group, and a third tape prepreg group repeatedly in the stated order on a forming die, in which grooves in a lattice shape are formed in three directions, so as to provide crossing regions in which two tape prepreg groups overlap each other, and a heating forming step of forming a laminate by heating under pressure. In the lamination step, the first tape prepreg group, the second tape prepreg group, and the third tape prepreg group are respectively laminated as one layer in crossing regions so that a tape width is maintained, and laminated in non-crossing regions in a state of being folded as two layers in a width direction thereof.
