Latent heat storage gypsum board and partition structure

A latent heat storage gypsum plate, comprising:

• a gypsum plate having a first main face and a second main face that is located on an opposite side of the gypsum plate from the first main face;
• and
• a latent heat storage layer disposed over at least part of the first main face of the gypsum plate, the latent heat storage layer including a latent heat storage material and a binder,
• wherein a heat storage capacity of the latent heat storage gypsum plate is 260 KJ/m2 or more, the heat storage capacity being measured in a measurement temperature range of 15° C. or higher and 35° C. or lower through heat storage capacity measurement specified in ASTM C 1784, and
• the latent heat storage gypsum plate exhibits heat generation property grade 1 as evaluated by a heat generation property test specified in JIS A 6901 (2014), with the first main face being set as a back face, and
• wherein the latent heat storage gypsum plate satisfies a relation of formula (1) below:
• Z≤126.48X+928.61Y−1732.0 (1)
• where X is a thickness (mm) of the gypsum plate, Y is a specific gravity of the gypsum plate, and Z is the heat storage capacity (kJ/m2).
