PURPOSE: To use the analyzer in a conveyer production system and simply analyzer components of material without depending on experts.

CONSTITUTION: A spark generation part 11 for generating a spark from a specimen is provided and the spark generated with the spark generation part 11 is converted into image information of three original colors of RGB with a camera and the like in an image input part 12. In regard to the image information a characteristic quantity of a spark image is learned and estimated with a characteristic extraction part 13 composed of a neural network. In addition, in regard thereto the complexity of the spark is calculated with a fractal dimension operation part 14, relation between the calculated value and a characteristic value of the spark image are judged with a synthetic judgment part 15 composed of fuzzy inference and component information of a specimen is obtained.
