Abstract: A high-frequency module includes first and second switch IC elements and a substrate. The first and second switch IC elements are the same or substantially the same IC chips, and are mounted in the same or substantially the same orientation. The first switch IC element is mounted on the substrate. The second switch IC element is mounted above the first switch IC element. Due to wire bonding, the individual pad electrodes of the first and second switch IC elements are connected to the land electrodes of the substrate, which are to be connected to the individual pad electrodes. Between a pad electrode and a land electrode connected to each other, another land electrode is not provided.
