The shell section (3) has: a tube-shaped side wall (6) that encircles the core section (2) with a gap therebetween; and a plurality of shell partition walls (7) that support the side wall (6) from the inside. The outer end (7b) of each shell partition wall (7) is connected to the side wall (6), and roundness is imparted to the corners formed by the shell partition walls (7) and the side wall (6).
