Abstract: The object of the present invention is to provide an analysis apparatus that makes it possible to detect lights from a plurality of spots formed on an analysis chip without the lack of positioning accuracy while detecting the lights and the instability of holding the samples in spite of the downsized construction thereof. To achieve such an object as mentioned above, the analysis apparatus of the present invention for analyzing samples by means of detecting lights from a plurality of spots formed on an analysis chip so as to hold the samples comprising: a chip holder for holding the analysis chip; a light-sensitive detector for detecting lights from the spots; and a selectively light-transmitting unit for transmitting lights selectively from the desired spots to the light-sensitive detector, in a state where the analysis chip is held by the chip holder.

Abstract: To improve convenience of a sensor unit using a transistor in analysis, a sensing gate for detection 117 of a sensor unit for detecting a detection target comprises a transistor part 103 having a substrate 108, a source electrode 111 and a drain electrode 112 provided on the substrate 108, a channel 113 forming a current path between the source electrode 111 and the drain electrode 112, and the sensing gate for detection 117 is provided with a gate body 115 fixed to the substrate 108 and a sensing part 116 capable of electrically conducting to the gate body 115 and on which a specific substance 123 capable of selectively interacting with the detection target is immobilized.
