A latent heat storage gypsum plate includes: a gypsum plate having a first main face and a second main face 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 and including a latent heat storage material and a binder. 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 from 15° C. through 35° C. through heat storage capacity measurement specified in ASTM C 1784. 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 face in which the latent heat storage layer is disposed being set as a back face.
