PROBLEM TO BE SOLVED: To provide a small high-functional communication module for mobile telephone. ! SOLUTION: A communication module 100' comprises: a circuit board 800 on which there are mounted a first high-frequency processing unit 610 involved in mobile phone communication, a second high-frequency processing unit 622 for processing a reception signal involved in a satellite positioning system, a system unit 630 including a baseband processing unit and an application processing unit, and a power supply circuit unit 640; a sealing member 900 that coats electronic components mounted on the circuit board 800; a conductive shield layer 901 formed on a surface of the sealing member 900; and a shield wall 902 formed in the sealing member 900 so as to separate a mounting region of the first high-frequency processing unit from a mounting region of the second high-frequency processing unit. !
