A sheet-like probe has a porous film. In the sheet-like probe, a contact
film is penetratingly supported at each position of through-holes formed
in the porous film, and a peripheral edge of the contact film and the
porous film are integrated such that a flexible resin insulation layer is
included in a fine hole of the porous film. Electrode structure bodies
are supported in a penetrating manner in the insulation layer. Each
electrode structure body includes a surface electrode section exposed to
the front surface of the insulation layer and projecting from the front
surface of the insulation layer, a back surface electrode section exposed
to the back surface of the insulation layer, a short-circuit section
continuously extending from the base end of the front surface electrode
section, penetrating the insulation layer in its thickness direction, and
connected to the back surface electrode section, a holding section
extending outward, along the front surface of the insulation layer, from
the base end section of the front surface electrode section, and a
supporting body supporting the insulation layer.
