A light and inexpensive heat storage member applicable to spacecrafts is provided. The heat storage member includes a honeycomb structural body (3) having a plurality of cells. Each of the cells is filled with a capsule, which contains a heat storage material, and a heat conductive filler. Since the capsule containing the heat storage material and the heat conductive filler are provided in the honeycomb structural body (3), the light and inexpensive heat storage member having favorable heat conductivity even when the storage member is thick can be provided. The heat storage member is provided by bringing a starting material (2) that is a mixture of the capsule containing the heat storage material and the heat conductive filler into contact with the honeycomb structural body (3) to cover at least one surface of the opening of the cells of the honeycomb structure body (3), subjecting the same to uniaxial pressure molding under the pressure of 4 MPa or more and 10 MPa or less, and filling each cell with the starting material (2). |
