The present invention relates to a process for preparing hypromellose hard capsule using thermogelation with improved storage stability, film strength, film distribution, filling up performance and/or bioavailability of ingredient. More specifically, this invention relates to a process for preparing hypromellose hard capsule using thermogelation with improved storage stability, film strength, film distribution, filling up performance and/or bioavailability of ingredient, comprising the steps of: i) sequentially adding and solubilizing 0.1-0.5 wt part of plasticizer, 0.1-0.5 wt part of wetting agent and a small amount of a viscosity stabilizer to the 100 wt part of hypromellose aqueous dispersion containing 19-22 wt part of hypromellose； ii) adjusting the viscosity of the mixture into 800-1,300 cP； iii) dipping the mold pin into the hypromellose aqueous solution maintained at 19-21 °C after preheating the mold pin to be 100-120 °C； and iv) forming the hypromellose hard capsule.
