Claim:
1. A sensor module comprising: a bottomed-cylindrical module body comprising a diaphragm; and a detector configured to detect a pressure, the detector being provided by coating a fluid conductive material to a flat portion of the diaphragm, wherein, the detector comprises: a plurality of resistor elements each configured to detect a strain; a pair of first and second resistor element electrodes, mutually opposed parts of each of the resistor elements being respectively overlapped with the pair of resistor element electrodes; and a linear conductor connected to an end of each of the pair of resistor element electrodes, the pair of resistor element electrodes each comprise: a linear portion having a linear inner side, the inner side of the first resistor element electrode facing the inner side of the second resistor element electrode; and peripheral portions on both ends of the linear portion, at least one of the peripheral portions being connected to the linear conductor, the linear portion being arranged so that all of the inner sides are parallel with each other, and the resistor element is connected with the linear portion and the peripheral portions are exposed without being connected with the resistor element.
