Blade body

A blade body, comprising:

• a plurality of signal terminals forming a metal strip shape that are disposed in parallel to each other, the plurality of signal terminals comprising an embedded part that is embedded and held in a base member made of an insulating material, and a protruding part that protrudes from the base member on one end side and is completely exposed from the insulating material, with the protruding part forming a connecting part that is electrically connected by contacting or solder-connecting to a mating connecting body;
• wherein the base member comprises a main body holding part that covers an entire circumference of the circumferential surface of the signal terminals and holds the signal terminals, and a semi-exposed holding part that exposes a portion of the circumferential surface of the signal terminals from the insulating material while covering and holding the remaining portion with the insulating material, with the protruding part of the signal terminals protruding from the semi-exposed holding part at one end side position with regard to the main body holding part;
• and
• at least a portion of the semi-exposed holding part is formed to be thinner than the main body holding part, and at least a portion of the embedded part corresponding to the main body holding part is formed to have a narrower terminal width than the protruding part;
• wherein the semi-exposed holding part holds the remaining portion and flexes with the protruding part when the signal terminals are flexed in a state of contact of a mating terminal.
