Abstract
A radio frequency module includes: a module substrate that includes a principal surface on which external-connection terminals are disposed; a power amplifier that is disposed on the principal surface of the module substrate and amplifies a radio frequency transmission signal; and a heat dissipator that dissipates heat of the power amplifier. The heat dissipator includes: a heat dissipation plate that covers a surface of the power amplifier which is opposite to a surface that faces the module substrate; and at least a first leg that extends from the heat dissipation portion toward the principal surface of the module substrate.
