Touch input device, vehicle including same, and manufacturing method therefor

A touch input device comprising:

• a touch portion having a concave portion and receiving a touch signal of a user;
• a parent material on which the touch portion is disposed;
• a base integrally combined with the touch portion or disposed at a lower side of the touch portion, the base having pattern grooves in an area corresponding to the touch portion;
• and
• sensing patterns comprising a conductive material and arranged on the pattern grooves,
• wherein the sensing patterns located at a lower side of the concave portion have a resistance smaller than that of the sensing patterns located at an outer side of the concave portion, and
• wherein the base comprises:
• a first base disposed at a lower side of the parent material;
• and
• a second base disposed at a lower side of the first base, and
• wherein the pattern grooves and the sensing patterns include:
• first pattern grooves and first sensing patterns formed on one surface of the first base;
• and
• second pattern grooves and second sensing patterns formed on one surface of the second base.
