To enhance compatibility of reducing insertion force and increasing holding force.SOLUTION: A press-fit terminal 20 comprises a press-fit portion 30 including two contact pieces 34 facing each other across an eye hole 31. The respective two contact pieces 34 include: parallel portions 36 in parallel with each other; front spring portions 35 extending from the parallel portions 36 in a direction in which the press-fit portion 30 is to be inserted; and rear spring portions 37 extending from the parallel portions 36 in a direction reverse to the direction in which the press-fit portion 30 is to be inserted. The press-fit portion 30 has a thickness equal to or longer than 0.3 mm and equal to or shorter than 0.5 mm. Ls/Le is equal to or larger than 0.57 and equal to or smaller than 0.65, where Le [mm] is a length of the eye hole 31 and Ls [mm] is a length of each of the parallel portions 36. G1/G2 is equal to or larger than 0.55 and equal to or smaller than 1.45, where G1 [mm3] is front side spring strength and G2 [mm3] is rear side spring strength.SELECTED DRAWING: Figure 1 【課題】挿入力を小さくすることと、保持力を大きくすることの両立性を高めることを目的とする。【解決手段】アイホール３１を隔てて対向する２つの接触片３４を含むプレスフィット部３０を備え、前記２つの接触片３４のそれぞれは、互いに平行な平行部３６と、前記平行部３６から前記プレスフィット部３０が挿入される向きに延びる前ばね部３５と、前記平行部３６から前記プレスフィット部３０が挿入される向きとは逆向きに延びる後ばね部３７とを含み、前記プレスフィット部３０の厚みは、０．３mm以上０．５mm以下であり、前記アイホール３１の長さをＬｅ［ｍｍ］とし、前記平行部３６の長さをＬｓ［ｍｍ］としたとき、Ｌｓ／Ｌｅが０．５７以上０．６５以下であり、前側ばね強さをＧ１［ｍｍ３］、後側ばね強さをＧ２［ｍｍ３］としたとき、Ｇ１／Ｇ２が０．５５以上１．４５以下であるプレスフィット端子２０である。【選択図】図１
