Abstract: The contact device includes an armature, a driver, a fixed contact, a movable contact, a contact spring, and a card. The driver drives 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 the movable contact to be in contact with and separate from the fixed contact. The card interconnects the armature and the contact spring. The card is made of resilient material and fixed to each of the armature and the contact spring.

Abstract: An electromagnetic relay includes a terminal electrically connected to a fixed contact or a movable contact, and a case accommodating a contact point. The terminal includes a terminal piece having at least a portion located outside the case. The case includes a bottom surface section (first peripheral wall section) and a side surface section (second peripheral wall section). The bottom surface section has a gap to be closed with a sealant and an outer surface to which the sealant is applied. The side surface section has a through hole through which the terminal piece is inserted. The case has a flow path along which the sealant applied to the outer surface flows from the outer surface to the through hole.

Abstract: In an electromagnetic relay, a connection terminal includes a first terminal section and a second terminal section. The first terminal section is accommodated in a base and is electrically connected to a coil. The second terminal section protrudes outside the base through a through hole and is electrically connected to an external connection body. The cover includes a second wall section provided to leave a space from a first wall section that has a through hole, and the second terminal section lies in the space. The space in which the second terminal section lies is sealed with a sealant.
