The contact device includes an armature, a driver, a fixed contact, a movable contact, a contact spring, a card, a case, and a positioning member. The driver is for driving the armature. The movable contact is to be in contact with and separate from the fixed contact. The contact spring is for holding the movable contact so as to allow movement of the movable contact. The card interconnects the armature and the contact spring. The case is a synthetic resin molded product. The positioning member is provided as a separate part from the case. The positioning member is for determining a positional relationship between the armature, the driver, the fixed contact, the movable contact, the contact spring, and the card, and is accommodated in the case.
