Claim Text:
1. A mobile terminal comprising: a case; a printed circuit board (PCB) arranged inside the case and having a surface on which a tamper detect pattern is mounted, the tamper detect pattern comprising a first and a second contact-type conductive patterns that are arranged adjacent to each other and a non-contact-type conductive pattern arranged apart from the first and the second contact-type conductive patterns, wherein the non-contact-type conductive pattern is electrically connected to the first contact-type conductive pattern or the second contact-type conductive pattern when a conductive liquid is injected into the temper detect pattern; a detection circuit electrically connected to the tamper detect pattern and detecting whether the tamper detect pattern is conductive; and a pattern conduction module arranged between the case and the PCB and controlling so that the first and the second contact-type conductive patterns are conductive when the case is assembled, and the conduction of the first and the second contact-type conductive patterns is released when the case is disassembled wherein the non-contact-type conductive pattern is provided in a center area of the tamper detect pattern, and wherein the first and the second contact-type conductive patterns are arranged around the non-contact-type conductive pattern that is used as an imaginary center, to be radially separated from each other.
