An electrical connection assembly includes a connector (CN) and a wiring material with conductors. The connector (CN) includes terminals (20) and an insulating housing (30) having a terminal holding portion (32) for holding the wiring material (10) such that the conductors are connected to the respective terminals (20). Each terminal (20) includes a held portion (22) and an outward projecting portion (24) projecting out from a surface (32a) of the terminal holding portion (32). The outward projecting portion (24) includes a first projecting portion (26) projecting in a first direction and a second projecting portion (27) extending from the first projecting portion (26) in a second direction closer to a direction parallel to the surface of the terminal holding portion (32) than the first direction. An outer surface of the second projecting portion (27) has a conductor connection surface (27a) connectable to the conductor extending in the second direction.
