Provided is a nucleic acid isolation method whereby it becomes possible to extract a nucleic acid in a simple manner without the need to use an alcohol. A nucleic acid isolation method, comprising the steps of: mixing a specimen containing a nucleic acid with an extraction solution to disperse the nucleic acid in the extraction solution; bringing the extraction solution containing the nucleic acid into contact with an anionic adsorbent; bringing a washing solution into contact with the anionic adsorbent; and bringing a collection solution into contact with the anionic adsorbent, the extraction solution containing a protein denaturant, the washing solution containing a basic compound and having a pH value equal to or less than a pKa value of a conjugate acid of the basic compound, and the collection solution having a pH value equal to or more than the pKa value of the conjugate acid of the basic compound.

Effectively control the temperature of a control unit of a railway equipment inspecting and measuring apparatus, and install the control unit of the railway equipment inspecting and measuring on the roof of the passenger car. The first space is formed between the control unit and the heat insulating case. The second space is formed between the heat insulating case and the cover. In the first space, heat is conducted between the air in the first space and the heat exchange element by the first heat conducting member, and the first fan causes circulation of the air in the first space. In the second space, heat is conducted between the air in the second space and the heat exchange element by the second heat conducting member, and the air inside the second space is diffused by blowing the air from a suction port into the second space with the second fan.
