Latent heat storage member and building material provided with same, microcapsules and thermal storage material using microcapsules

摘要

The present invention is to provide a latent heat storage member which is able to more reliably contribute to a daily peak shift of energy consumption, and a building material provided with the latent heat storage member. A latent heat storage member 20 which is formed by using a material including a latent heat storage material such as paraffin and a gelation agent and is used as a building material, includes an outer side surface 20b arranged on a solar light irradiation side facing the outside, and has a phase change temperature T1 within a temperature range between a lowest temperature Tsmin and a highest temperature Tsmax of the outer side surface 20b in the daytime.
