Connector, connector assembly, and wearing article

A connector that is configured to be mounted on a mounting object and fitted to a counter connector in which a counter first contact and a counter second contact are retained by a housing having rigidity and an insulating property, the connector comprising:

• a first contact and a second contact that are spaced from each other in a predetermined direction and are configured to be respectively fitted to the counter first contact and the counter second contact when the connector is fitted to the counter connector;
• and
• a first sheet member that has flexibility and an insulating property and is stretchable at least in the predetermined direction, a base end of the first sheet member in the predetermined direction being mounted on the mounting object at a position opposite from the second contact with respect to the first contact, and a distal end of the first sheet member in the predetermined direction having the first contact retained therein,
• wherein the second contact is configured to be retained by the mounting object via a second sheet member having flexibility and an insulating property or directly retained by the mounting object, and
• with at least the first sheet member being elastically stretched in the predetermined direction, the connector is fitted to the counter connector, and due to a shrinking force generated at the first sheet member, the first contact and the second contact are electrically connected to the counter first contact and the counter second contact, respectively.
