PROBLEM TO BE SOLVED: To provide a contact arrangement unit, capable of minimizing the space between contacts inserted to a through-hole formed in a plate. SOLUTION: An IC socket 10 comprises a contact 20, in which a first flange part 21b is disposed in a clearance S1 between an upper plate 13 and a middle plate 14x, the first flange part 21 having an outer diameter d2 larger than diameter D2 of an upper through-hole 11a of the upper plate 13, and a second flange part 22b is disposed in a clearance S2 between the middle plate 14y and a lower plate 15, the second flange part 22b having an outer diameter d4 larger than diameter D4 of a lower through-hole 15a of the lower plate.
