Abstract
A hydrogel structure (10) includes: a continuous phase (11) of a first hydrogel; and a dispersion phase (12) of a second hydrogel, the dispersion phase being dispersed in the continuous phase (11). A ratio of a local minimum value of a load after break to a breaking load (a local minimum value of a load after break/a breaking load) of the hydrogel structure (10) is 0.1 or more.
