摘要:
A double-walled hollow panel (A) has a first wall (21) and a second wall (22) which are made of thermoplastic resin and arranged separated from each other. Longitudinal inner ribs (11) and lateral inner ribs (12) arranged so as to cross the longitudinal inner ribs (11) are formed in a space (V) between the first and second walls (21, 22) so as to extend through the first wall (21) and be fusion bonded to the second wall (22). The longitudinal inner ribs (11) and the lateral inner ribs (12) are integrated together via crossing sections (13). Each crossing section (13) has a hole (H) not fusion bonded to the second wall (22), and the holes (H) interconnects adjacent small spaces.
