Disclosed is a mobile terminal provided with a security function. The mobile terminal provided with the security function, according to one embodiment of the present inventive concept, comprises: a casing comprising a data input portion for inputting data, and an upper casing and a lower casing which can be assembled and disassembled; a circuit board, which is electrically connected to the data input portion and is provided with a security unit that requires security, for processing inputted data; a tamper prevention conductive portion which is arranged between the casing and the circuit board and is electrically connected to the circuit board by means of pressing when the upper casing and the lower casing are assembled, and a control portion for denying access to data in the security unit based on a resistance value of the tamper prevention conductive portion. As a result, access to data in a secure region to which important data is saved is denied when the casing is forcibly opened, thereby effectively preventing important data from being leaked to the outside.
