Abstract
A partition member includes an encapsulated body capable of retaining a liquid and an outer package body having an internal space for accommodating the liquid and the encapsulated body in a sealed state. The ratio of a water absorption rate 2 to a water absorption rate 1, [water absorption rate 2]/[water absorption rate 1], is at least 0.4. The water absorption rate 1 indicates the water absorption rate when the encapsulated body is compressed for 1 minute at a pressure of 0.05 kgf/cm, and the water absorption rate 2 indicates the water absorption rate when the encapsulated body is compressed for 1 minute at a pressure of 5 kgf/cm.
