Abstract

See full text

There are provided a connection structure of printed circuit boards, and so forth, the connection structure including a first printed circuit board, a second printed circuit board located above the first printed circuit board, and an anisotropic conductive adhesive configured to establish a conductive connection between a conductor of the first printed circuit board and a conductor of the second printed circuit board, in which the anisotropic conductive adhesive contains a conductive filler, and in which the conductive filler is formed of crystallized metal-particle wires produced by allowing metal particles to crystallize and grow linearly. It is thus possible to easily achieve sufficiently high connection strength while a flying lead of one printed circuit board is electrically connected to a conductive lead (substrate pad) of the other printed circuit board.
