PURPOSE: An instrument panel unit of a vehicle with a radio signal receiver is provided to improve receiving performance of signals by forming a meter housing, a display unit arranged in the meter housing, a meter circuit board and the radio signal receiver connected to the antenna. CONSTITUTION: An instrument panel unit(11) of a vehicle incorporates a radio signal receiver(5) formed on a circuit board(6) which is fixed over a meter circuit board(4) in parallel thereto within a meter housing(21). An antenna inlet(63) on the circuit board is located in one outer region among longitudinally trisected regions of the meter circuit board. The meter circuit board works efficiently as the additional part of the antenna, thereby improving the signal receiving performance inclusive of the antenna gain of the receiver. The segment of the antenna is extended longitudinally, and placed in parallel to the surface of the meter circuit board. The circuit pattern is arranged around the edge of the meter circuit board to form the radio signal receiving pattern of closed loop in the high frequency circuit.
