Abstract: A detector provided on a flat portion of a diaphragm includes a plurality of strain gauges, resistor element connectors connecting adjacent ones of the strain gauges, and an electric conductor covering a part of the resistor element connectors. First linear portions and second linear portions of the resistor element connectors exposed from the electric conductor are orthogonal to the edges of the electric conductor extending across the first linear portions and the second linear portions. Even when a pattern of the resistor element connector and a pattern of electric conductor are misaligned in X direction or in Y direction, an area of the resistor element connector exposed from the electric conductor does not change.
