1. A cover member comprising:
a first substrate including a first surface and a second surface on an opposite side of the first surface, the first surface being a detection surface for detecting an object in contact with or in proximity to the first surface and detecting a shape of the object; and
a sensor provided under the first substrate, and including first electrodes and second electrodes,
wherein
the first electrodes are configured to detect the shape of the object independently of the second electrodes,
the second electrodes are configured to detect positional coordinates of the object independently of the first electrodes,
a size of each of the second electrodes is greater than a size of each of the first electrodes,
a shape of each of the second electrodes is different from a shape of each of the first electrodes,
the first electrodes are provided between the first substrate and the second electrodes in a first direction perpendicular to the first surface, and
one of the second electrodes overlaps the first electrodes.
