A high-frequency module, comprising:

• a reception portion that processes a reception signal received by a reception antenna;
• and
• a transmission portion that processes a transmission signal to be supplied to a transmission antenna, wherein:
• said reception portion includes:
• a first demultiplexer circuit that divides the reception signal among plural reception lines having different frequency bands from each other;
• said transmission portion includes:
• plural power amplifier circuits that respectively amplify power of transmission signals in different frequency bands;
• and
• a second demultiplexer circuit that supplies outputs of said power amplifier circuits to said transmission antenna;
• and
• said first demultiplexer circuit included in said reception portion, and said power amplifier circuits and said second demultiplexer circuit included in said transmission portion, are provided in a multi-layer substrate.
