1. A position detection sensor, comprising:
a base made of a flexible material, and having a first surface;
a terminal section having a plurality of terminal conductors disposed therein, and formed on the first surface of the base; and
a sensor pattern section including a plurality of electrode conductors formed of coated conducting wires, arranged in predetermined patterns, and disposed on and adhered to the base via an adhesive in an area that does not overlap with the terminal section on the first surface of the base, wherein end portions of the coated conducting wires of the plurality of electrode conductors are positioned so as to be connectable to corresponding ones of the terminal conductors in the terminal section, wherein
the first surface of the base includes a region of the terminal section, a region of the sensor pattern section, and a bendable region between these two regions wherein the bendable region spans a first distance between these two regions,
the end portions of the plurality of electrode conductors of the sensor pattern section are electrically connected to the plurality of terminal conductors in the terminal section through the bendable region,
each of the plurality of electrode conductors includes a first portion having a length of the first distance and an extra room portion having an additional length, such that the plurality of electrode conductors are extensible in the bendable region between the terminal section and the sensor pattern section, wherein no adhesive is applied to the bendable region, and
the extra room portion includes a wound portion in the bendable region to be extensible in the bendable region.
