An object of the present disclosure is to make it possible to improve electrical inspection of an object to be inspected by making the conduction characteristics of the electrical signal flowing through an electrical contactor better. An electrical contactor according to the present disclosure includes: a pedestal portion having, at a lower end thereof, a contact portion that comes into contact with a first contact target of an object to be inspected; a base end portion extending continuously toward an installing portion that comes into contact with a second contact target of a substrate electrically connected to an inspection device side; and at least three or more arm portions provided between the base end portion and the pedestal portion, each of the at least three or more arm portions having one end supported by the base end portion and another end coupled to the pedestal portion to elastically support the contact portion.
