HIGH FREQUENCY MODULE

Abstract

A high frequency module includes: a line substrate having a first high-frequency signal line on a first surface thereof and a second high-frequency signal line on a second surface being a surface on the opposite side of the first surface, the second high-frequency signal line being electrically connected with the first high-frequency signal line; and a base substrate which is provided to the second surface of the line substrate, and which is formed in a manner that the base substrate is located away from the second high-frequency signal line.
