Abstract: By a manufacturing method including a process of supplying a connection-releasable connecting material (4) onto a surface of a plurality of chip parts (3) and a process of connecting the plurality of chip parts (3) by the connecting material (4), there is formed a chip assembly (1) comprised of the plurality of chip parts (3) connected with each other by means of the releasable connecting material (4). Further provided is a method of preparing the chip assembly (1), a process of releasing connection achieved by the connecting material (4) between a target chip part and an adjacent chip part, and a process of mounting the target chip part separated through releasing of the connection onto a board and soldering the same, thereby providing chip parts capable of easily coping with an increase of operation speed of chip parts on the process of mounting line, achieving an improved space efficiency, and suppressing waste of resources.
