The area surrounding one end of the connection electrode 213 may be formed at a portion where stress is concentrated in the connection electrode 213 when heat and pressure are applied.

According to the above configuration, it is possible to effectively prevent a phenomenon in which a crack occurs in the connection electrode 213 during thermocompression bonding.

At this time, a portion of the pad electrode 214 surrounding the connection electrode 213 may be formed with a reinforcing portion 241 ′ a having a thicker thickness than other regions.

Accordingly, the breakdown voltage and heat resistance of the connection terminal of the touch window 240 connected to the connection cable 250 can be improved.

The above-described mobile terminal and its manufacturing method are not limited to the configuration and method of the above-described embodiments, but the embodiments may be selectively or partially all of the embodiments so that various modifications may be made. It may be configured in combination.
