As shown in FIG. 2 , the electrode part 122 has a shape in which a plurality of electrode parts 122a and 122b are spaced apart from each other in the longitudinal direction. Each of the electrode parts 122a and 122b is formed in the same shape, and the adjacent electrode parts 122a and 122b are not electrically connected.
