A three-dimensional sensing device includes a pressure sensing film, a silver nanowire electrode, a first touch sensing electrode layer, and a second touch sensing electrode layer. The pressure sensing film includes a substrate and a polarized pressure sensing layer. The polarized pressure sensing layer is disposed on and in contact with a first side of the substrate. The silver nanowire electrode is disposed on a side of the polarized pressure sensing layer opposite to the substrate. The first touch sensing electrode layer is disposed on and in contact with a second side of the substrate and includes a patterned electrode with burr etching. The patterned electrode includes first-axis electrodes. A gap between adjacent two first-axis electrodes is between 20 &#x3bc;m to 35 &#x3bc;m. The second touch sensing electrode layer is disposed on a side of the first touch sensing electrode layer opposite to the polarized pressure sensing layer.
