[PROBLEMS] To provide a connection board ensuring individual connections between a large number of external contacts of an electronic component and a large number of spiral contacts of a board by so arranging the electronic component and the board that the external contacts are opposed to the spiral contacts and bringing the external contacts into contact with respective spiral contacts positively. [MEANS FOR SOLVING PROBLEMS] A connection board (CB) is provided in which a relay board (20) on both sides of which provided are spiral contacts (24A, 24B) are opposed to a guide member (30) having small holes (31) into which the spiral contacts (24A) and external contacts (2a) provided to an electronic component (1) are individually inserted from both directions. The diameters of the small holes (31A) provided in at least two corners of the guide member (30) out of the holes (31) thereof are smaller than that of the other small holes (31). When the electronic component (1) is mounted, the external contacts (2a) in the corner of the electronic component (1) are positioned by the positioning small holes (31A) in the corner, and therefore, the other external contacts (2a) can be positioned with respect to the other small holes (31). |
