PROBLEM TO BE SOLVED: To provide a corrosion testing device constituted so as to prevent a leak of the gas in a test tank to keep the component ratio of the corrosive gas in the test tank constant and capable of keeping the concentration distribution of the corrosive gas in the test tank constant to perform a safe test excellent in reproducibility. SOLUTION: The device is constituted so that a sample is housed in the test tank having a main body and an upper lid and the corrosive gas is introduced into the test tank to perform a corrosion test and has a gas introducing means, an exhaust means, a gas concentration measuring means and a detection means for detecting the hermetic closing degree in the test tank in its test tank. This corrosion testing machine is also provided with an exhaust treatment device having a test tank sucking means and a hermetic closing degree test tank hermetic closing degree adjusting means for adjusting the joining of the main body and upper lid of the test tank corresponding to the hermetic closing degree detected by the test tank hermetic closing degree detecting mans.
