PURPOSE: A power feeding device of a mobile communication terminal is provided to supply a ground pattern and a power feeding pattern to an internal circuit board, and to fix a monopole antenna connected to the power feeding pattern by a support, thereby obtaining a space in a terminal case and implementing a simple power feeding structure. CONSTITUTION: An internal circuit board(5) supplied in a terminal case configures a circuit related to mobile communication control and power feeding, and has a power feeding line(5b) on a rear side. A double-faced substrate(7) has a vertical part(7a) adhered to a back of the internal circuit board(5), has a horizontal part(7b) by extending the vertical part(7a), has a ground pattern(11), and supplies another power feeding line(13) connected to the power feeding line(5b). Coupling members(15,17,19) connect the internal circuit board(5) with the vertical part(7a) of the double-faced substrate(7). An antenna support(9) pierces through the horizontal part(7b), and has a space inside. A monopole antenna(3) is inserted into the antenna support(9), and is electrically connected to the power feeding line(13) of the horizontal part(7b).
