PROBLEM TO BE SOLVED: To provide a substrateless double-sided adhesive sheet capable of easily discriminating a double-sided releasing film laminated on an adhesive layer through visual observation, in a step of bonding a member by using the substrateless double-sided adhesive sheet. ! SOLUTION: In a substrateless double-sided adhesive sheet 10 in which each of polyester films 13, 14 and 23, 24 having releasing layers 15 and 25 are laminated on both surfaces of an adhesive layer 11 through the releasing layers 15 and 25, at least one polyester film has a laminated structure, and contains a polycyclic aromatic hydrocarbon compound or an organometallic chelate complex in intermediate layers 13 and 23 excluding outermost layers 14 and 24 in the laminated structure. !
