PURPOSE: A diplexer is provided to reduce a parasitic component by forming the circuit structure of capacitors, in which high pass filters are connected in a delta shape, and an inner pattern structure. CONSTITUTION: A branch node(N1) is connected to an antenna. The branch node receives a signal. A low pass filter(310) receives a received signal through the branch node. A low pass filter passes through a low band signal which is included in the received signal. A high pass filter(320) passes through a high band signal which is included in the received signal and a first, a second, and a third capacitor which are connected in a delta shape.
