Claim Text:
1. A method for manufacturing a probe card, comprising: preparing a connection base plate having a surface provided with a plurality of connection pads with which a plurality of probes are to be coupled; preparing the plurality of probes each having a connecting end portion to the connection pad; preparing a holding plate having formed therein in a plate thickness direction through holes which make the respective connecting end portions of the probes opposed to the corresponding connection pads and which hold the connecting end portions; holding the probes in the holding plate in a state in which the respective probes are arranged in the corresponding through holes and in which the connecting end portions of the respective probes project from one surface of the holding plate; arranging a plate-like member by making one surface of the plate-like member abut on the one surface of the holding plate, the plate-like member penetrated by openings, formed to correspond to the through holes and having at least equal or larger diameters to or than diameters of the through holes, and having a thickness sufficient to house the connecting end portions in the openings; supplying solder cream in the respective openings from the other surface of the plate-like member so as to bury the respective connecting end portions of the probes housed in the respective openings of the plate-like member; and after the supply of the solder cream, heating the solder cream for melting of the solder cream for the purpose of coupling the connecting end portions of the respective probes with the respective connection pads in a state in which the connection base plate and the holding plate are relatively fixed so that the solder cream, burying the connecting end portions of the respective probes held in the holding plate in a state in which the plate-like member has been removed, may abut on the respective corresponding connection pads of the connection base plate.
