Information input device configured to detect shear force

An information input device comprising:

• a cover panel;
• a housing including a support portion that supports a peripheral edge of the cover panel from a back surface;
• a frame-shaped shear force sensor disposed between the peripheral edge of the cover panel and the support portion of the housing, the shear force sensor detecting a horizontal input with respect to a surface of the cover panel;
• and
• a detection circuit connected to the shear force sensor, wherein
• the frame-shaped shear force sensor has a structure in which a first electrode member, an elastic member, and a second electrode member are layered in this order from a side of the cover panel,
• the first electrode member includes:
• a first substrate having at least a frame portion;
• a band-like first electrode disposed in a linear pattern on an opposed surface that is closest to the elastic member of the first substrate;
• and
• a first lead-out wiring line provided on the first substrate and connected to the first electrode,
• the second electrode member includes:
• a second substrate having at least a frame portion;
• a pair of band-like second electrodes disposed on an opposed surface that is closest to the elastic member of the second substrate so as to be in parallel to the first electrode and partially overlap with the first electrode in a plan view;
• and
• a second lead-out wiring line disposed on the second substrate and connected to the second electrode, and
• the elastic member covers all of the first electrode and the pair of second electrodes.
