Abstract
A partition member includes an encapsulated body capable of retaining a liquid, and an outer package body for accommodating the encapsulated body and the liquid. The area S1 of the encapsulated body when the outer package body and the encapsulated body are seen in a planar view from the thickness direction and the area S2 of a gap between the outer package body and the encapsulated body satisfy the relationship represented by formula 1 below, and the volume V1 of the liquid and the volume V2 of the encapsulated body satisfy the relationship represented by formula 2 below. S1/(S1+S2)≤0.99 and Formula 10.02≤V1/V2≤1.90 Formula 2
