A syringe for intratympanic injection, which allows secure recognition that an infusion in the syringe is at a temperature within a temperature range suitable for the administration into the tympanic cavity just before injection is provided. A syringe for tympanic injection 10 for direct injection of an infusion in a barrel 12 into the tympanic cavity, having first and second reversible temperature indicators 20.25 provided on an outer surface 12b of the barrel, wherein an indication based on difference temperatures at which the reversible temperature indicators 20.25 change in color allows visual recognition of a range of injection temperature suitable for administration into the tympanic cavity. In this way, the range of injection temperature suitable for administration into the tympanic cavity can be indicated in a way that allows visual recognition, and by seeing the reversible temperature indicators 20, 25 just before injection, a user of the syringe for tympanic injection 10 can certainly recognize that the infusion in the barrel 12 is at a temperature within the temperature range suitable for the administration into the tympanic cavity.
