A tuner module includes a circuit board, an electronic component, mounted on the circuit board, for demodulating a high frequency reception signal received from an antenna unit to produce a speech signal, a metal case accommodating the circuit board and the electronic component therein, and a heat conductive sheet, disposed between the electronic component and the metal case, made of an elastic body. The heat conductive sheet has dimensions which are substantially equal to or slightly lower than outer dimensions of the electronic component. The metal case has at least one slit-shaped hole which is formed along an outer shape of the electronic component.
