To provide an apparatus for producing methyl iodide without using a pumping means while effectively utilizing 11CH4.
The apparatus is provided with an inert gas flow channel 1 to supply an inert gas from an inert gas source, a methane supplying device 2 to supply 11CH4 to the inert gas flow channel, a methyl iodide forming vessel 3 to form 11CH3I by reacting 11CH4 with iodine, a methyl iodide collector 4 to collect the 11CH3I, a chamber 5 to hold a gas, and a flow channel switching device 80 to selectively switch the first state to connect the inert gas flow channel 1, the methyl iodide forming vessel 3, the methyl iodide collector 4 and the chamber 5 in the order in series and the second state to connect the inert gas flow channel 1, the chamber 5, the methyl iodide forming vessel 3 and the methyl iodide collector 4 in the order in series.
