Abstract
The present disclosure provides a portable electronic device and an active capacitive stylus thereof. The active capacitive stylus includes a pen-shaped casing structure, a support structure, a circuit substrate, a sensor module, an elastic assembly, an abutting assembly, a pen head structure and a power supply component. The circuit substrate is positioned on the support structure. The sensor module is electrically connected to the circuit substrate. The elastic assembly includes a flexible holder contacting the sensor module and a flexible element disposed between the flexible holder and the sensor module. The abutting assembly is disposed inside the pen-shaped casing structure to abut against the flexible holder. The pen head structure, the abutting assembly, the elastic assembly and the sensor module are abutted one to another, so that there is no gap between two of the pen head structure, the abutting assembly, the elastic assembly and the sensor module.
