To provide a contactor capable of processing a shaft easily, and having no possibility of generating abrasion or damage early on a contact ball.
In this contactor, a contacting contact ball 30 is stored rollably with a part of a spherical surface exposed to the outside, in a storage hole 23 formed on a tip part of the shaft 20, and a plurality of support balls 40 for support are interposed between the inner bottom surface of the storage hole 23 and the contact ball 30. A storage part 25 having a larger inner diameter than the front side end is formed on the inner side end of the storage hole 23, and a continuous flat surface 23a orthogonal to the axial center of the shaft 20 is formed on a portion positioned at least on the outer circumferential side on the inner bottom surface of the storage hole 23, and the contact ball 30 is stored in the storage hole 23 in the state where the plurality of support balls 40 are allowed to abut on the inner circumferential surface 25a of the storage part 25 and on the flat surface 23a.
