Abstract
A pressure sensor device includes an electrically insulative substrate, a base electrode layer, spacer portions, a guard electrode layer, and a membrane plate. A sensing electrode portion and monitoring electrode portions are located on the membrane plate and face the substrate. In a case where the monitoring electrodes are mounted on a circuit board, the monitoring electrodes detect at least one of stress or strain occurring in or on the spacer portions.
