1. A biochip, comprising:
- a large number of spots containing a plurality of types of capture solutions arranged on a base plate by means of an ink jet system, said plurality of types of said capture solutions each being adapted to specifically react with a specimen and provide information about a structure within the specimen, wherein each of said spots has a plurality of types of capture material, and said spots are formed at a same spot formation position.

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.
