  • the top surface portion TP has a first portion P1 extending in the left-right direction.
  • the width WWP of the wide portion WP in the front-rear direction is wider than the width WP1 of the first portion P1 in the front-rear direction. Therefore, the distance in the front-rear direction between the wide portion WP of the first signal terminal 13a and the first ground terminal 14a is shorter than the distance in the front-rear direction between the wide portion WP of the first signal terminal 13a and the first portion P1 of the first signal terminal 13a. Therefore, the value of the parasitic capacitance formed between the wide portion WP of the first signal terminal 13a and a part of the first ground terminal 14a facing the wide portion WP of the first signal terminal 13a in the front-rear direction is large.
  • the value of the parasitic capacitance formed between the top surface TP of the first signal terminal 13a and a part of the first ground terminal 14a facing the top surface TP of the first signal terminal 13a in the front-rear direction is small. If the first contact portion CP1 of the first signal terminal 13a were to exist only on a virtual extension line of the top surface portion TP of the first signal terminal 13a, the value of the parasitic capacitance formed between the first contact portion CP1 of the first signal terminal 13a and a part of the first ground terminal 14a that faces the first contact portion CP1 of the first signal terminal 13a in the front-rear direction would also be small.
  • the value of the parasitic capacitance formed between the first signal terminal 13a and the part of the first ground terminal 14a changes greatly depending on the position of the first signal terminal 13a in the left-right direction.
  • the front-to-rear width WCP of at least a portion of the first contact portion CP1 of the first signal terminal 13a is wider than the front-to-rear width WP1 of the first portion P1.
  • the front-to-rear distance between the first contact portion CP1 of the first signal terminal 13a and the first ground terminal 14a is shorter than the front-to-rear distance between the first contact portion CP1 of the first signal terminal 13a and the first portion P1 of the first signal terminal 13a.

This allows the value of the parasitic capacitance formed between the first contact portion CP1 of the first signal terminal 13a and a part of the first ground terminal 14a facing the first contact portion CP1 in the front-rear direction to be closer to the value of the parasitic capacitance formed between the wide portion WP of the first signal terminal 13a and a part of the first ground terminal 14a facing the wide portion WP of the first signal terminal 13a in the front-rear direction.
  • the change in the value of the parasitic capacitance formed between the first signal terminal 13a and a part of the first ground terminal 14a due to a change in the left-right position can be reduced. Therefore, according to the first connector 10, the parasitic capacitance formed between the terminals can be leveled. As a result, impedance mismatch can be suppressed and return loss can be reduced.
  • the horizontal length of at least a portion of the first contact portion CP1 of the first signal terminal 13a is greater than the vertical thickness TP1 of the first portion P1.
  • Parasitic capacitance increases not only when the opposing distance between the terminals is shortened, but also when the opposing area between the terminals is increased. Therefore, even in this case, the value of the parasitic capacitance formed between the first contact portion CP1 of the first signal terminal 13a and the portion of the first ground terminal 14a that faces the first contact portion CP1 of the first signal terminal 13a in the front-rear direction increases.
  • the horizontal length of at least a portion of the first contact portion CP1 of the first signal terminal 13a is greater than the vertical thickness TP1 of the first portion P1, so that the parasitic capacitance formed between the terminals can be leveled out.
  • the first contact portion CP1 of the first signal terminal 13a overlaps with the back portion BP when viewed in the left-right direction. This allows the vertical length of the first signal terminal 13a to be shortened. Therefore, the vertical length of the first connector 10 can be shortened.
  • the first connector 10 can further reduce return loss. More specifically, when first signal terminals through which high frequency signals are input and output are adjacent on the first straight line L1, mutual induction between adjacent first signal terminals causes the first signal terminal to be affected by the high frequency signal flowing through the adjacent first signal terminal, resulting in return loss. Therefore, in the first connector 10, the first signal terminal is located between adjacent first ground terminals or first power supply terminals on the first straight line L1. This allows the first ground terminal or first power supply terminal to suppress the influence of the high frequency signal flowing through the first signal terminal, further reducing return loss.
  • the first signal terminal and the second signal terminal of the second connector 110 can be more reliably contacted. More specifically, the first protrusion PP1 of the first contact portion CP1 has a second portion P2 extending forward from the top surface TP. Furthermore, the second protrusion PP2 of the first contact portion CP1 has a fourth portion P4 extending rearward from the top surface TP. In the connector set 1, the first signal terminal contacts the second signal terminal on the right surface of the first contact portion CP1. Since the first protrusion PP1 of the first contact portion CP1 has the second portion P2 and the second protrusion PP2 of the first contact portion CP1 has the fourth portion P4, the area of the right surface of the first contact portion CP1 is increased. As a result, according to the first connector 10, the first signal terminal and the second signal terminal of the second connector 110 can be more reliably contacted.
  • the parasitic capacitance formed between the terminals can be more reliably equalized.
  • the first protrusion PP1 of the first contact portion CP1 has a third portion P3 extending leftward from the second portion P2.
  • the second protrusion PP2 of the first contact portion CP1 has a fifth portion P5 extending leftward from the fourth portion P4. This makes it possible to increase the area in which the first contact portion CP1 of the first signal terminal 13a and a portion of the first ground terminal 14a face each other in the front-rear direction.
  • the first protrusion PP1 and the second protrusion PP2 of the first contact portion CP1 may be press-fitted into the first body member 11. In this case, the first signal terminal is reliably supported by the first body member 11.
