Abstract: A heat retaining container (70) includes: an accommodating space (71); and walls (72) including inner surfaces surrounding the accommodating space (71). Heat conductivity of each wall (72) in a surface direction is higher than heat conductivity of the wall (72) in a thickness direction orthogonal to the inner surface of the wall, the surface direction being orthogonal to the thickness direction and extending along the inner surface of the wall.
