Abstract
An embodiment of the invention provides a method for manufacturing a probe sheet in which a probe tip can be arranged at a predetermined accurate position without the need for troublesome positional adjustment operations of the probe tip in coupling operations of each contactor and a probe sheet main body. It is a method for manufacturing a probe sheet comprising a probe sheet main body having conductive paths and a plurality of contactors formed to be protruded from one surface of the probe sheet main body and connected to the conductive paths. The manufacturing method comprises the steps of forming a plurality of the contactors on a base table by sequentially depositing on the base table metal materials for a plurality of contactors from their respective probe tips toward base portions with use of a photolithographic technique, forming on the base table the probe sheet main body to be coupled with the base portion of each contactor held on the base table, and separating the contactors from the base table integrally with the probe sheet main body.
