Abstract
A probe unit having a plurality of elongate leads disposed longitudinally in an array on a surface of an insulative sheet. Tip portions of the leads aligned along an end edge of the sheet are capable of being brought into contact, under pressure, with corresponding electrode pads of an electronic part. An insulative material is embedded in at least those areas of grooves between the tip portions of the leads. Slots, which are smaller in width than the leads, are formed between the tip portions of the leads. The tip portions of the leads have a reduced width and are longitudinally disposed on wide comb tooth like pieces of the insulative sheet isolated by the slots, and the insulative materials isolated by the slots are longitudinally intimately disposed along the opposite ends of the tip portions of the leads.
