A combination terminal (1) has a first terminal (10) overlapping a second terminal (110) in a plate thickness direction. The first terminal (10) includes a base (41) and two inclined walls (20) intersecting surfaces of the base (41) from both lateral ends of the base (41) and forming an insertion/accommodation space (C) having a trapezoidal shape. The second terminal (110) includes an inserting piece (132) that overlaps the base (41) when inserted into the insertion/accommodation space (C). A locking claw (132A) on the inserting piece (132) locks the base (41) by overlapping the inserting piece (132) on the base plate (41). An external force absorbing tapered portion (133) projects laterally from the inserting piece (132) and comes into surface contact with one of the inclined walls (42) with the locking portion (132A) locked to the base (41).
