The utility model relates to a mould survey device, it includes that stratum lucidum, protective layer and laminating paste the layer between stratum lucidum and protective layer, pastes the layer and is equipped with the trompil, lies in the trompil and scribbled and to determine mycotic culture medium on the stratum lucidum, the protective layer can be torn so that paste laminating in the position that awaits measuring, realizes the culture medium and the position contact of awaiting measuring from this. The culture medium was observed to survey personnel's permeable stratum lucidum change judges whether the portion of awaiting measuring exists the mould, but its is rational in infrastructure, easy operation, need not special equipment field operation.
