Claim 6:
7. The sensor device of claim 1, wherein
the panel further comprises a plurality of third electrodes provided on the second main surface side of the insulating layer and electrically insulated from each other,
the first electrode and the second electrode are located in a first area,
the plurality of third electrodes are located in a second area outside the first area and are arranged at intervals from each other along the second area,
the first circuit further includes a plurality of second amplifiers electrically connected to the plurality of third electrodes on a one-to-one basis,
during the first sensing drive period,
the timing control circuit outputs a plurality of fifth synchronization signals generated based on the first synchronization signal and having a polarity inverted from the polarity of the first synchronization signal, and
each of the second amplifiers amplifies the corresponding fifth synchronization signal and provides the amplified fifth synchronization signal to the corresponding third electrode, and

an amplitude of the fifth synchronization signal amplified by each of the second amplifier is greater than an amplitude of the second synchronization signal amplified by the first amplifier.
