Abstract
To provide an electrical connection unit that enables miniaturization. [Solution] An electrical connection unit 1 according to an aspect of the present invention comprises a semiconductor relay 2 including a pair of connection terminals 2a and 2b, a pair of bus bars 3a and 3b arranged on both sides of the semiconductor relay 2, and a control board 4 arranged on the side facing the semiconductor relay 2. The bus bars 3a and 3b have a joint portion 31 to which the connection terminals 2a and 2b are joined, and an upright portion 32 that rises from the opposite side of the joint portion 31 toward the side facing the control board 4. The semiconductor relay 2 is arranged with the joint portions 31 of the pair of bus bars 3a and 3b connected. The control board 4 is arranged with the upright portions 32 of the pair of bus bars 3a and 3b connected.
