1. Assembly parts for a connector device comprising:
a substrate having a through hole;
a press-fit terminal that is a rod shape member and that is to be press-fitted into the through hole,
wherein the press-fit terminal includes, in order from a leading end side of the press-fit terminal, a leading end portion, a press-fit portion, and a base end portion,
the press-fit portion includes:
an eye hole that penetrates through the press-fit terminal in a thickness direction of the press-fit terminal;
a parallel portion that includes two contact pieces that are parallel with each other and are separated by the eye hole; and
a tapered portion that connects the parallel portion and the leading end portion to each other, and
a thickness of the press-fit terminal is at least 0.4 mm and at most 0.5 mm,
in a vertical cross section of the press-fit terminal taken at positions where the thickness of the press-fit terminal is bisected,
the eye hole is provided with a curved line that constitutes a leading end-side portion of the eye hole,
lines that constitute the tapered portion each include a contact point and a reference point,
the contact points are located closer to the leading end portion than the reference points are,
the contact points are points that first come into contact with an opening edge of the through hole when the press-fit terminal is inserted into the through hole,
the reference points are intersections of (i) the lines that constitute the tapered portion and (ii) lines that are orthogonal to the lines that constitute the tapered portion and pass through end points of the curved line.
