A contact device, comprising:
- a fixed contact member including a fixed contact;
- and
- a movable contact member which includes a movable contact and is movable between a position where the movable contact is in contact with the fixed contact and a position where the movable contact is away from the fixed contact;
- a first contact member which is one of the fixed contact member and the movable contact member further including a protrusion which protrudes from a main face to which a first contact is provided, in a direction which is the same as a protruding direction of the first contact, which protrudes toward a second contact of a second contact member which is an other of the fixed contact member and the movable contact member,
- the protrusion being formed by folding an end part of the first contact member,
- a shortest distance between a tip of the protrusion and the first contact being shorter than a shortest distance between a folded part of the first contact member and the first contact.
