Abstract
A heat storage and conduction sheet (3, 4, 5) of the present invention includes: a heat storage sheet (1, 1a, 1b) including a matrix resin and heat storage inorganic particles; and a heat diffusing material (2, 2a, 2b) that is united with the heat storage sheet. The heat storage inorganic particles are composed of a material that undergoes an electronic phase transition and has a latent heat of 1 J/cc or more for the electronic phase transition. The amount of the heat storage inorganic particles is 10 to 2000 parts by mass with respect to 100 parts by mass of the matrix resin. The heat storage sheet has a heat conductivity of 0.3 W/m·K or more. The heat diffusing material has a heat conductivity in a planar direction of 20 to 2000 W/m·K. Thus, the present invention provides a physically stable heat storage and conduction sheet having high heat storage properties and high heat conduction properties, and excellent heat diffusion properties in a planar direction.
