  If the suspect left his/her fingerprints at a crime scene, depending on the types of crimes, i.e. whether it was a crime by the resident of the scene, crime by the person who had been in the scene, or crime by the person who discovered the crime, etc., the time when they were impressed often becomes a point of issue in the trial.
  Although some data on the change in the quality of fingerprints over time were already reported, they were based only on those that were over a short period of time.
  The change of the quality of fingerprints varies by individual differences, conditions when they were impressed, types of objects on which fingerprints were impressed, and conditions of places where fingerprints were kept.
  In this report, we conducted the experiment on the change of quality of fingerprints over a long period of time (seven years ago from now, and to be continued for another three years).
  The data of aging impressed fingerprints will contribute to scientific investigation.
