A ground connecting member is connected to a ground formed on a substrate. The ground connecting member has elasticity and conductivity. The substrate is fixed on a compensating member for compensating for an area of the ground. At this time, the ground connecting member is sandwiched between the substrate and the compensating member. In this structure, the ground connecting member contacts the compensating member, and electrically connects the ground with the compensating member in a low impedance state.
