Abstract: A three-dimensional, electronic components mounted wiring body comprises a flat wiring body, on which a plurality of electronic components is mounted, and which is preformed with bends to be configured into a three-dimensional structured flat wiring body which fits the shape of a base structure on which the flat wiring body is to be mounted. An electronic components mounting structure is provided by mounting the three-dimensional, electronic components mounted wiring body on the three-dimensional base structure which is assembled from base members and their joining members. Connectors having piercing members are used to electrically and mechanically connect the electronic components to the flat wiring body.

Abstract: An electronic components mounted wiring body (10) comprises a flat wiring body (2) on which a plurality of electronic components (20) is mounted, and a plurality of base members (31) on which the flat wiring body (2) is mounted. The flat wiring body (2) has arrangement direction changing folds (9), each of which is designed to change an arrangement direction of the electronic components (20) of the flat wiring body (2). Each base member (31) has an arrangement direction changing member (37) which is designed to fix the arrangement direction changing fold (9). The base members (31) are joined using joining members (32) so that the electronic components mounted wiring body (10) is configured into a three-dimensional shaped electronic components mounting structure (1).
