Abstract: An active stylus, including a housing, a pen core, a first circuit board, and a touch sensing module, is provided. The pen core, the first circuit board, and the touch sensing module are disposed in the housing. The touch sensing module includes a touch sensing element and a second circuit board. The touch sensing element is disposed on and electrically connected to the second circuit board. The second circuit board is electrically connected to the first circuit board and is abutted to a lateral surface of the first circuit board. The second circuit board is perpendicular to the first circuit board. The pen core is abutted to the touch sensing element.

Abstract: An active stylus including a pen housing, a pen core module disposed in the pen housing, a control module disposed in the pen housing, and an elastic member assembled to the control module and the pen core module is provided. The pen core module has a first end and a second end opposite to each other. The first end is protruded out of the pen housing. The control module has a force sensing element, and an elastic force of the elastic member drives the second end of the pen core module to be abutted to the force sensing element seamlessly.
