## Abstract

Disclosed is a touch input device capable of inputting a touch signal, a vehicle having the same, and a manufacturing method thereof. A touch input device comprises: a touch portion including a concave portion and receiving a touch signal of a user; a base integrally combined with the touch portion or disposed at a lower side of the touch portion and having pattern grooves in an area corresponding to the touch portion; and sensing patterns having a conductive material and arranged on the pattern grooves. The sensing patterns located at a lower side of the concave portion have a resistance smaller than a resistance of the sensing patterns located at an outer side of the concave portion.

## Claims

### Claim 1

A method of manufacturing a touch input device, the method comprising steps of:
preparing a parent material comprising a concave portion preparing a base comprising a metal complex at a lower side of the parent material;
forming pattern grooves by irradiating a laser to a touch portion of the base, wherein the pattern grooves comprise pattern grooves in an area in which the concave portion is located and pattern grooves in an area at an outer side of the concave portion are different from each other in at least one of a width and a depth; and
forming sensing patterns including a conductive material in the pattern grooves through a plating process or a deposition process.

### Claim 2 (depends on 1)

The method according to claim 1, wherein the pattern grooves have at least one of a width and a depth larger than at least one of a width and a depth of the pattern grooves.

### Claim 3 (depends on 1)

The method according to claim 1,
wherein metal seeds are exposed to inner surfaces of the pattern grooves in the step of forming the pattern grooves by irradiating the laser on one surface of the base, and
wherein the conductive material is attached to the metal seeds in the plating or depositing of the sensing patterns.

### Claim 4 (depends on 3)

The method according to claim 3,
wherein the step of forming the pattern grooves comprises forming first pattern grooves and second pattern grooves disposed apart from the first pattern grooves,
wherein the step of forming the sensing patterns comprises forming first sensing patterns to be plated or deposited on the first pattern grooves and second sensing patterns to be plated or deposited on the second pattern grooves, and
wherein the method further comprises determining whether or not the first and second sensing patterns are in condition for use as a sensor by providing a current to the first and second sensing patterns and by inspecting a change in mutual capacitance between the first and second sensing patterns.
