A rupture disc assembly is provided to stably engage a rupture disc by preventing damage to the rupture disc. A rupture disc assembly includes a mounting recess section(710), a plug section(720), a rupture disc(300), and a pressing ring(500). The mounting recess section is formed on an outer wall surface of a pressure container and is communicated with the interior space of the pressure container by a communication hole. The plug section is engaged with the mounting recess section and the interior of the plug section is opened. The rupture disc is ruptured if the pressure in the interior of the pressure container exceeds a set value. The rupture disc includes a dome section and a peripheral section. The pressing ring is interposed between the plug section and the rupture disc to press the peripheral section of the rupture disc.
