Biochip
First Claim
1. A biochip comprising a large number of spots of capture material arranged on a base plate, obtained by supplying, onto said base plate by means of an ink jet system, a plurality of types of capture solutions, each said capture material being adapted to specifically react with a specimen and provide information about a structure within the specimen, wherein:
- a plurality of said spots, which have different spot sizes, are formed on said base plate, wherein all of said spots have uniform detection sensitivity.

Abstract
When the genetic analysis is performed by using a DNA microarray, the inspection accuracy is improved. A sample solution is supplied onto a base plate to prepare the DNA microarray comprising a large number of spots based on the sample solution arranged on the base plate. In the microarray, the planar configuration of the spot is substantially circular, and a plurality of spots having different spot sizes are formed on the base plate.
