Abstract: An electrical connection structure according to the present disclosure includes a glass plate, a power supply part formed on the glass plate, a connection terminal including a base part facing the glass plate, and a spring member disposed between the power supply part and the base part and configured to electrically connect the power supply part to the base part. The spring member includes a fixing part, a curved part, and contact parts. The curved part includes branch parts branched by a slit. The contact part is disposed at each of end parts of the branch parts. The contact parts are in contact with the base part independently of each other. The curved part is in contact with the power supply part at a part protruding toward the glass plate.
