Provided is a heat storage body production method with which it is possible to adjust the specific surface area and the heat capacity, and that can be arranged easily, reducing dead space. A ceramic cylindrical body (50) extending in a single axial direction Z and having a plurality of through-holes (10), which have a circular or elliptical shape in a cross section orthogonal to the axial direction, at a density of (2 to 50)/in2 in the cross section orthogonal to the axial direction is drilled once with a cylinder (51) in a direction X that is orthogonal to the axial direction Z. Further, it is also possible to drill once more with the cylinder in a direction orthogonal to the axial direction Z and the direction X. |
