Abstract: A sensor package 10 includes a plurality of sensors 19 and a container 18. Each of the sensors 19 detects a detection target component in the fluid. The container 18 includes an inner channel 21 and a first surface os1. The plurality of sensors 19 are provided in the inner channel 21. The inner channel 21 enables the fluid to flow. An inflow opening 25 to the inner channel 21 and an outflow opening 25 from the inner channel 21 are formed on the first surface os1. An electrode group electrically connected to the plurality of sensors 19 is provided on a surface different from the first surface os1 of the container 18.

Abstract: A sensor package 10 includes a container 18 and a plurality of sensors 19. The container 18 includes inside an internal flow path 21 allowing a fluid to flow in a first direction d1 having linearity. The plurality of sensors 19 is located in the internal flow path 21 and arrayed in the first direction d1. The sensors 19 detect a component to be detected within the fluid.
