PURPOSE:To obtain inexpensively a device having a simple structure and functioning as a small oxygen generator by allowing a chemical reaction of a deriv. of H2O2 to be caused in saturated and heat insulated condition under pressure by using the H2O2 deriv. in combination with a soln. of a decomposition catalyst. CONSTITUTION:A small oxygen generator is constituted of a deriv. of H2O2 (e.g. sodium percarbonate, urea peroxide, etc.), and soln. of decomposition catalyst (0.05-5wt% basing on the weight of the H2O2 deriv.) in water (5-100wt% basing on the weight of the H2O2 deriv.). A starting pin 11 is connected to a separating film (bag) 9 (made of a plastic material, etc.) provided with a blade knife 10 between the H2O2 deriv. 1 and the decomposition catalyst 2. When the starting pin 11 is pulled, the content is brought into contact with each other and mixed (the reaction is caused in a reaction section 4, 5). Generated oxygen is purified in a moment and cooled (by passing through filters 6, 7, 8), and pure oxygen is discharged from an exit 12. The pressure of the oxygen is adjusted by a pressure control valve 3.
