The present invention relates to a directional coupler, in particular, to a capacitance compensation type directional coupler comprising a signal line for transmitting signals. A coupling line is formed apart from and parallel to the signal line, with its first end transmitting the extracted power and its second end terminated. At least one conductive line, electrically connected to the coupling line, is extended from the coupling line across the signal line, apart from and perpendicularly overlapping with the signal line. The present invention compensates capacitance between the signal line and the coupling line by forming capacitance in areas where the conductive line and the signal line overlapping each other perpendicularly.
