Board-to-board connector

A board-to-board connector that is interposed between a first board and a second board, the board-to-board connector thus electrically connecting a plurality of pads of the first board to a plurality of respective pads of the second board, the board-to-board connector comprising:

• a housing;
• and
• a plurality of contacts held on the housing, wherein
• when a direction in which the first board and the second board are opposed to each other is called a board opposing direction,
• each of the contacts includes a holding part, a connecting part, and a spring part,
• the holding part having a longitudinal axis which is extended in the board opposing direction and is held on the housing by press fitting,
• the spring part includes a contact part, an extended part, and a projection part,
• the projection part is extended in the board opposing direction and is opposed to the holding part,
• the connecting part connects an end part of the projection part on the side of the first board and an end part of the holding part on the side of the first board, the connecting part further being able to come in contact with a corresponding pad of the first board,
• the extended part is extended from an end part of the projection part on the side of the second board in such a way that the extended part passes between the holding part and the second board on the longitudinal axis of the holding part, and
• the contact part is disposed in the extended part in such a way that the contact part comes into contact with a corresponding pad of the second board.
