Abstract

An electronic device includes a substrate, a base substrate, a metal connection body, a support body, a metal body, and a via. The substrate includes one main surface with a functional element and is a piezoelectric substrate or a compound semiconductor substrate. The substrate is mounted on the base substrate such that the one main surface faces the base substrate. The metal body is in contact with the support body and includes at least a portion extending to outside the substrate in plan view from the support body. The via connects the portion of the metal body outside the substrate and the base substrate to each other and has a higher thermal conductivity than the substrate.
