A contact device comprising
- a first conductive portion including a first end portion and a first extended portion, the first end portion including a first contact, the first extended portion being provided to extend in one direction and connected to the first end portion at a tip in the one direction of the first extended portion, and
- a second conductive portion including a second end portion and a second extended portion, the second end portion including a second contact, the second extended portion being provided to extend in the one direction and connected to the second end portion at a tip in the one direction of the second extended portion,
- one contact selected from the group consisting of the first contact and the second contact being a moving contact, the other contact selected from the group consisting of the first contact and the second contact being a fixed contact,
- the moving contact being configured to move between a closed position where the moving contact is in contact with the fixed contact and an open position where the moving contact is out of contact with the fixed contact,
- at least the first end portion, out of the first end portion and the second end portion, being curved to be folded back from a tip in the one direction of the first end portion,
- the first contact being located in a folded-back part of the first end portion and facing the second contact,
