Abstract:
There is provided a pressure sensing device including a plate-shaped member, plural strain sensitive materials arranged on the plate-shaped member, and a connection electrode electrically connected to a predetermined circuit. The plate-shaped member includes a surface portion having a center portion that receives force applied to a tip portion of a stylus. The plural strain sensitive materials include first and second strain sensitive materials arranged at different distances from the center portion of the surface portion of the plate-shaped member. The plural strain sensitive materials are formed on at least one surface portion of the plate-shaped member along with a conductive pattern that connects the first and second strain sensitive materials. The connection electrode is electrically connected to the plural strain sensitive materials, and the connection electrode is crimped and electrically connected to the predetermined circuit housed in the stylus.
