DIGITIZER

A digitizer includes a flexible printed circuit film including a folding area capable of being folded and unfolded; a plurality of first lines disposed on the first surface of the flexible printed circuit film and extending in a first direction; and a plurality of second lines disposed on the second surface, which is opposite to the first surface, of the flexible printed circuit film and extending in a second direction crossing the first direction. The first lines and the second lines define a grid area overlapping the folding area on a plane, and the flexible printed circuit film includes a penetration hole in the grid area. 数字化仪包括：柔性印刷电路膜，包括可实现折叠和展开的折叠区域；多个第一布线，配置在柔性印刷电路膜的第一面上，并且在第一方向上延伸；以及多个第二布线，配置在柔性印刷电路膜的与第一面相反的第二面上，并且在与第一方向交叉的第二方向上延伸，在平面上定义在第一布线与第二布线之间的多个格子区域之中的与折叠区域重叠的格子区域中，形成有贯通柔性印刷电路膜的贯通孔。
