Abstract
The invention offers a board-connecting structure that can provide electrodes with a fine pitch and that can combine the insulating property and the connection reliability. The structure of connecting printed wiring boardsandelectrically connects a plurality of first electrodesandprovided to be adjacent to each other on a first boardwith a plurality of second electrodesandprovided to be adjacent to each other on a second boardthrough an adhesivethat contains conductive particlesand that has anisotropic conductivity. By heating and pressing the adhesive placed between the mutually facing first electrodeand second electrodeand between the mutually facing first electrodeand second electrode, an adhesive layeris formed between the first boardand the second boardand in the adhesive layer, a cavity portionis formed between the first electrodesandand between the second electrodesand
