摘要:
A detector is provided by coating a fluid conductive material on a flat portion of a diaphragm. The detector includes: a resistor element (3); resistor element electrodes (4), which are overlapped and connected with mutually opposed parts of the resistor element (3); and a linear conductor connected with the resistor element electrodes (4). The resistor element electrodes (4) each include: a linear portion (40S) having a linear inner side facing an inner side of paired one of the resistor element electrodes (4); and peripheral portions (40E) defined at both ends of the linear portion (40S), at least one of the peripheral portions (40E) being connected with the linear conductor. All of the linear portions (40S) are arranged so that inner sides (40L) are arranged mutually in parallel. The resistor element (3) is connected with the linear portion (40S). The peripheral portions (40E) are exposed without being connected with the resistor element (3).

A torque sensor (1) includes: a first area (2) having a first surface (21) and a second surface (22) opposite the first surface (21); a second area (3) provided around the first area (2); a plurality of beams connecting the first area (2) to the second area (3); and a detector provided on the first surface (21) of the first area (2) and configured to detect torque applied between the first area (2) and the second area (3). The detector includes: an insulation film (51) layered on the first area (2); and strain gauges layered on the insulation film (51) and being deformable in response to torque. The second surface (22) of the first area (2) is provided with screw holes (23) that do not reach the first surface (21) and into which fasteners are respectively screwed. A thickness (H) defined between a bottom of each of the screw holes (23) and the first surface (21) is equal to or more than one fourth of a diameter (M) of each of the screw holes (23).

A pressure sensor has a stem (10) in which a pressure introduction hole into which a pressure medium is introduced and a diaphragm (13) deformable according to the pressure of the pressure medium are formed, and a strain detecting element (30) which is arranged on the diaphragm (13) via an insulating film (20) and being configured to output a detection signal according to the deformation of the diaphragm (13). The strain detecting element (30) is configured to have a portion made of polysilicon. A low doping layer (23) having a higher electrical resistivity than polysilicon and a higher crystallinity than the insulating film is arranged between the insulating film (20) and the strain detecting element (30).

摘要:
A detector (20) provided on a flat portion of a diaphragm (10) includes a plurality of strain gauges (3), resistor element connectors (4) connecting adjacent ones of the strain gauges (3), and an electric conductor (6) covering a part of the resistor element connectors (4). First linear portions (411, 421, 431, 441) and second linear portions (412, 422, 432, 442) of the resistor element connectors (4) exposed from the electric conductor (6) are orthogonal to the edges (61A, 61B, 62A, 62B, 63A, 63B, 64A, 64B) of the electric conductor (6) extending across the first linear portions (411, 421, 431, 441) and the second linear portions (412, 422, 432, 442). Even when a pattern of the resistor element connector (4) and a pattern of electric conductor (6) are misaligned in X direction or in Y direction, an area of the resistor element connector (4) exposed from the electric conductor (6) does not change.
