It is an object of the present invention to provide an on-off type fluorescent compound (a fluorescence-producing molecule system) used in gene analyses, which is highly stable (namely, being active for a long period of time) and highly sensitive, and which enables amplification of a trace amount of gene signal and observation thereof. The present invention provides a nonfluorescent molecule having a fluorescent substance skeleton such as fluorescein skeleton and having a group represented by —O—C(Y1)(Y2)-N
