1. A sensor device including an operation surface on which an input operation is performed, the sensor device comprising:
an insulating substrate;
a touch sensor that comprises sensor electrodes formed on one main surface of the insulating substrate;
a blocking body that is disposed on the one main surface;
a detecting electrode that is disposed to face the blocking body; and
a spacer that keeps a space between the blocking body and the detecting electrode, the spacer including a first surface and a second surface located opposite to the first surface,
wherein
the first surface is located closer to the operation surface than the second surface,
the detecting electrode is disposed on the second surface,
the blocking body and the detecting electrode constitute a pressure-sensitive sensor that detects a change in capacitance value caused by approaching of the blocking body and the detecting electrode,
the blocking body blocks capacitive coupling between an operator and the detecting electrode caused by approaching of the operator to the operation surface,
the touch sensor further comprises a first shield portion that is disposed on the one main surface,
at least a part of the first shield portion is formed in at least a part of a periphery of the sensor electrode, and
the blocking body is included in the first shield portion,
the first shield portion is separated from the sensor electrode and surrounds the sensor electrode,
the first shield portion comprises a shield wiring disposed between the sensor electrodes.
