Electronic parts loaded module.

摘要

An electronic parts loaded module comprises a circuit board having electronic parts connected thereto via a plurality of projecting electrodes (11), in which two or more of the plurality of projecting electrodes (11) for connecting the electronic parts have a narrowed portion (1102 between one end (1101) adjacent to the boundary for connection with the electronic parts and the other end (1103) adjacent to the boundary for connection with the board, the narrowed portion (1102) having a cross-section which has different dimensions in crossing directions, or a minor axis and a major axis different in length from each other. The projecting electrodes (11) are disposed in a manner as the larger dimension or the major axis being aligned along the periphery or the side of the electronic parts, or as surrounding the central area of the surface, on which the electronic parts are loaded. The module can be used in IC cards and liquid crystal display apparatuses and the like.
