- the sensor package 10 of the present embodiment configured as described above includes an internal channel 21 in which a plurality of sensors 19 are provided and through which a fluid flows, an inflow port to the internal channel 21 and an outlet from the internal channel 21.

Since the FPC generally undulates, it is difficult to stably press the sensor package 10 against the package mounting surface 42 by pressing via the FPC 33. Outlet sealing may be compromised. On the other hand, the sensor module 11 having the configuration described above can press the sensor package 10 at a position separated from the FPC 33, so that it can press stably.

- the sensor package 10 can reduce overall fluid retention in the internal flow path 21 and shorten the retention time. Therefore, the sensor package 10 may improve the responsiveness of each sensor 19 after fluid has entered the sensor package 10 . Since the responsiveness of each sensor 19 is improved, the sensor package 10 can detect odors due to a combination of detection target components of each of the plurality of sensors 19 with high detection accuracy. Further, in the sensor package 10 having the above configuration, the pressure in the internal flow path 21 is equalized, so detection errors due to differences in pressure to the plurality of sensors 19 are reduced. Therefore, the sensor package 10 can further improve the odor detection accuracy.
- the plurality of sensors 19 are positioned on the planar bottom surface bs.
- the sensor package 10 does not form a continuous plane between the bottom surface bs and the detection surface ds of the sensor 19, but has a recessed step with respect to the detection surface ds. This step can homogenize the flow velocity of the fluid between the detection surface ds and the top surface ts. Although such action is not theorized, it is presumed as follows. Since the fluid has viscosity, it is considered that the flow velocity of the fluid flowing along the plane whose entire surface is flat decreases in the vicinity of the plane.
- a fluid flowing along a surface having a recessed step with respect to the detection surface ds experiences a decrease in flow velocity in the vicinity of the surface where the detection unit 39 is formed due to the recessed step. It is thought that the flow velocity of the fluid between the detection surface ds and the top surface ts can be homogenized.
- both ends of the internal channel 21 in the first direction d1 are tapered away from the center of the internal channel 21 when viewed from the normal direction of the bottom surface bs,
- the container 18 is formed with an inflow/outlet port 25 near the tip of the tapered shape at both ends of the internal flow path 21 .
- the outflow/outlet port 25 is defined by a cylindrical inner peripheral wall surface perpendicular to the bottom surface bs.
- the sensor package 10 can cause the fluid flowing into the internal channel 21 from the inlet/outlet 25 to collide with the bottom surface bs, so that the pressure in the entire internal channel 21 can be equalized.
- the fluid easily flows into the space surrounded by the side surface of the sensor 19, the side surface of the step portion 23, and the bottom surface bs.
- the fluid can easily flow in the space surrounded by the bottom surface bs and between the sensors 19. FIG. As a result of these, the sensor package 10 can suppress stagnation of the fluid and increase the flow velocity of the fluid along the first direction d1.
- the container 18 includes a body portion 37 having a depression and a lid portion 38 in which the outflow port 25 is formed.
- a flow path 21 is formed.
- the container 18 is made of ceramic.
- the sensor package 10 can prevent the components of the container 18 from being mixed into the fluid due to liquefaction or vaporization of the container 18 body. Therefore, the sensor package 10 can suppress deterioration in detection accuracy of the detection target component.
- the sensor package 10 of this embodiment includes a heater 20 . Therefore, in the sensor package 10, by heating the internal flow path 21 and the sensor 19 using the heater 20, the fluid adsorbed to the internal flow path 21 and the sensor 19 is desorbed, and the internal flow path 21 can be refreshed. Further, in the sensor package 10, the heater 20 reduces temperature fluctuations in the internal flow path 21, so it is possible to suppress deterioration in detection accuracy of the component to be detected regardless of temperature changes in the fluid to be detected. Further, by changing the temperature of the sensor 19 with the heater 20 to change the detection sensitivity and selectivity of the sensor 19, the detection accuracy of the component to be detected can be improved.
- stepped portions 23 extending in the first direction d1 are formed on both sides of the bottom surface bs in the second direction d2.
- the sensor package 10 collects more fluid between the detection surface ds and the top surface ts of the sensor 19, increases the flow velocity, and shortens the fluid arrival time.
- the connection wiring 41 closer to the side surface ss1 in the second direction d2 than the detection section 39, the fluid can smoothly flow over the detection section 39, and the flow velocity of the fluid on the detection section 39 can be reduced.
- the side surface ss1 is positioned apart from the sensor 19 along the second direction d2 between the detection surface ds and the top surface ts of the sensor 19 . Therefore, in the sensor package 10, between the surface where the detection portion 39 is formed and the top surface ts, a decrease in the flow velocity of the fluid in the vicinity of the end portion in the second direction d2 is suppressed. It is possible to reduce the difference in flow velocity due to the difference in the position of If the entire side surface ss1 is separated from the sensor 19, the volume of the internal flow path 21 increases and the flow velocity decreases as a whole.
- the sensor package 10 does not separate the entire side surface ss1 from the sensor 19. Therefore, while suppressing the overall decrease in flow velocity, the difference in flow velocity in the area that contributes to the improvement of the detection accuracy is reduced. can be reduced.
- the height of the stepped portion 23 with respect to the bottom surface bs is equal to or higher than the height of the sensor 19 .
- the sensor package 10 narrows the space between the stepped portion 23 and the top surface ts, thereby allowing more fluid to flow over the sensor 19 and increasing the flow velocity.
- the sensor package 10 can shorten the residence time of the fluid and shorten the detection time difference between the detection units 39 of the sensors 19, thereby improving the detection accuracy of the component to be detected.
- the sensor electrode 40 and the stepped electrode 24 are connected by the connection wiring 41 in order to transmit the signal output by the detection unit 39 to the outside of the sensor package 10 .
- This wiring structure suppresses a decrease in the flow velocity of the fluid due to the connection wiring 41 on the sensor 19, and improves the detection accuracy of the component to be detected.
- the sensor module 11 of the present embodiment draws in the fluid by the pump portion 15 provided in the flow path 16 and supplies the fluid to the sensor package 10 .
- the fluid supplied to the sensor package 10 is switched between the test fluid and the reference fluid by switching between the first channel 17a and the second channel 17b by the switching unit 13 . Therefore, regardless of whether the fluid supplied to the sensor package 10 is the test fluid or the control fluid, the same pump portion 15 draws the fluid downstream. If the pump that supplies the test fluid to the sensor package 10 is different from the pump that supplies the control fluid, there will be a difference in the amount of supply of the test fluid and the control fluid due to the difference in the performance of each pump. may occur.
- the fluid supplied to the sensor package 10 is controlled by the single pump unit 15, so that the sensor module 11 is more stable than when different pumps are used for different fluids to be supplied. can be used to supply fluid to the sensor package 10 .
- conditions for supplying the test fluid and the control fluid to the sensor package 10 tend to be equal.
- sensor package 10 is more likely to detect test and control fluids under more equal conditions. Therefore, according to the sensor module 11, it is possible to improve the measurement accuracy of the component to be detected.
