1. A digitizer comprising:
a base member comprising a front surface and a rear surface opposing the front surface;
first sensing lines disposed on the base member, arranged in a first direction, and extending in a second direction crossing the first direction; and
second sensing lines disposed on the base member, spaced apart from the first sensing lines, arranged in the second direction, and extending in the first direction,
wherein the digitizer detects an external input by an electromagnetic resonance (EMR) method,
the base member is foldable about an imaginary folding axis extending in the second direction and is provided with a through-hole penetrating at least a portion thereof, and
the through-hole is surrounded by the first sensing lines and the second sensing lines, and
the through-hole has a width equal to or greater than about 10 micrometers and equal to or smaller than about 300 micrometers in the first direction.
