1. A capacitive touch panel comprising:
a touch panel section comprising a plurality of drive electrodes to which a drive signal is supplied, a plurality of pressure detecting electrodes, and a plurality of position detecting electrodes; and
a cover member disposed at a touch surface side of the touch panel section,
wherein of the plurality of pressure detecting electrodes and the plurality of position detecting electrodes, a pressure detecting electrode and a position detecting electrode are alternately arranged in a first direction,
the plurality of drive electrodes is arranged side by side in a second direction that is orthogonal to the first direction in plan view,
each of the plurality of pressure detecting electrodes comprises a plurality of pressure detecting sections that is arranged side by side in the second direction, and that each independently detects a pressure,
each of the plurality of position detecting electrodes comprises a plurality of position detecting sections that is arranged side by side in the second direction, and that each independently detects a touched position,
in the touch panel section, an area of at least one of the plurality of pressure detecting sections is larger than an area of at least one of the plurality of position detecting sections, and
the area of the at least one of the plurality of pressure detecting sections is not less than 2.5 times and not more than 7.3 times as large as the area of the at least one of the plurality of position detecting sections.
