PROBLEM TO BE SOLVED: To make the pickup voltage hard to be dropped without spreading current distribution from spreading in a connection device for an electric supply line. SOLUTION: The connection device 1 includes: a pair of blade receiving spring portions 3 that hold therebetween each of end parts spaced apart and facing each other of a power supply line 2 and are electrically connected to the power supply line 2; and a flexible conductor 4 that electrically connects the blade receiving spring portions 3 to each other. The blade receiving spring portions 3 each include: a contact member 31 that is in contact with the power supply line 2 with a small electric resistance; and spring members 32 that hold therebetween the contact member 31 and the power supply line 2 from both sides. The spring members 32 are each made of a material with higher electric resistance than the contact member 31. Since the spring member 32 has a higher resistance than the contact member 31, a current flows mainly through the contact member 31 and does not flow through the spring members 32, preventing the current distribution from spreading, and this prevents the pickup voltage from dropping.
