Provided is a tire puncture sealant that is excellent in storage stability and sealability after heat cycle. A volume V 1 obtained by containing a synthetic resin emulsion, a tackifier, and an antifreezing agent, and drying the synthetic resin emulsion at 20 ° C. for 12 hours and further drying at 50 ° C. for 10 hours. The synthetic resin emulsion film was immersed in a mixed solution containing 100 parts by mass of propylene glycol and 100 parts by mass of water at 80 ° C. for 7 days. The volume V 2 of the synthetic resin emulsion film after the test is measured, and the volume V 1 and the volume V 2 are expressed by Equation (1): Volume swelling rate (%) of the synthetic resin emulsion film = (V 2 −V 1 ) / Tire puncture, in which the volume swelling ratio of the synthetic resin emulsion film is 0 to 30%, which is obtained by applying to V 1 × 100 Wood.
