Abstract: Provided is a high-frequency module that can prevent a transmission signal from reaching a reception circuit and that can achieve high mounting density. A first duplexer for a first frequency band is mounted on a circuit substrate, and a second transmission filter and a second reception filter that constitute a second duplexer for a second frequency band are embedded in the circuit substrate. The second transmission filter and the second reception filter are embedded in the circuit substrate in locations that overlap at least a part of a projection region that is formed by projecting the first duplexer in a thickness direction of the circuit substrate. The first frequency band and the second frequency band are separated from each other by at least a prescribed frequency range.
