PROBLEM TO BE SOLVED: To provide an element which allows formation of a small-sized electronic device and in which a break-off part is formed such that a breaking part of the break-off part lies inside a contour of an element piece that restricts a gap between the element piece and an element piece housing part of a package.SOLUTION: A substrate 10 comprises: a plurality of individual pieces 1; a pair of coupling parts 3a, 3b extending from each of the individual pieces 1; and a holding part 2 to which extension ends of the coupling parts are connected. Each of the coupling parts includes a constricted part between an individual-piece connection part to which the individual piece is connected and a holding-part connection part to which the holding part is connected. Each of the individual piece includes a salient 1d which extends from an end of the individual-piece connection part of the individual piece between the pair of coupling parts in an extension direction of the coupling parts. The constricted part is provided a position closer the individual-piece connection part than an end in the extension direction of the salient.
