Abstract
A touch input device including a connection member electrically connecting a sensor electrode and a printed circuit board by contact without soldering may include a base including a metal complex, an electrode groove formed by irradiating a laser on the base, a sensor electrode formed on the electrode groove through a plating or deposition process and including a conductive material, a sensor IC to sense a change in capacitance of the sensor electrode, a printed circuit board on which the sensor IC is mounted and is disposed to be coupled with the base, and the connection member provided on the printed circuit board and configured to electrically connect the sensor electrode and the printed circuit board, wherein the connection member may elastically come into contact with the sensor electrode to connect the sensor electrode and the printed circuit board.
