A connection structure comprises a cable and a connection object. The cable includes two wires and an insulation body which covers and binds the two wires. The insulation body includes two coverings which cover the wires, respectively. The connection object comprises a base portion and a pressing member. The base portion has a catch portion and a cable-holding portion. The cable has a held section and a pressed section. The held section is held by the cable-holding portion. The pressed section is sandwiched and pressed between the pressing member and the catch portion in an upper-lower direction (Z-direction). The insulation body of the pressed section includes a coupling strip. The coupling strip couples the two coverings to each other in a lateral direction (Y-direction).
