A tablet production apparatus comprising a gas generator G, a lubricant powder discharge means 51 for discharging a lubricant powder into a gas generated from the gas generator G, depending on the supply of the gas from the gas generator G, and mixing the lubricant powder with the gas in dispersed state, a lubricant application means 91 for spraying the lubricant powder discharged from the lubricant powder discharge means 51 and mixed with the gas generated from the gas generation means G in dispersed state, onto each material contacting surface of a die, an upper punch and a lower punch, and an oxygen concentration measuring means 131a for measuring the oxygen concentration of the gas existing near the lubricant application means 91. The apparatus is designed such that the amount of the gas supplied into the lubricant application means is adjusted based on the oxygen concentration measured by the oxygen concentration measuring means 131a.
