PROBLEM TO BE SOLVED: To reduce an insertion loss for a route of a receiving signal in a high frequency module in which an element for outputting a receiving signal in the status of a balanced signal is mounted on the upper surface of a layered substrate and a receiving signal terminal is disposed on a bottom surface of the layered substrate. SOLUTION: A high frequency module comprises a layered substrate 200 and an element 120 for outputting a receiving signal in the status of a balanced signal. The element 120 includes output terminals T1, T2 and is mounted on an upper surface 200b of the layered substrate 200. Receiving signal terminals Rx1, Rx2 are disposed on a bottom surface 200a of the layered substrate 200. The high frequency module 1 comprises signal paths SP1, SP2 connecting the output terminals T1, T2 and the receiving signal terminals Rx1, Rx2. The signal paths SP1, SP2 are configured using one or more through-holes provided within the layered substrate 200, respectively, and are not exposed on a side surface of the layered substrate 200.
