PROBLEM TO BE SOLVED: To provide brush-shaped electrodes for an inspection device, which detects pinholes of a hermetically sealed packed object by a changes in the current of the electrodes brought into contact with a part where the content exist in the object simultaneously while the electrodes maintain the separating state when the hermetically sealed packed object is transported, without causing V-shaped hair cracks due to a circular arc-shaped cross section of the object to be inspected, which results in defects in inspection. SOLUTION: Contact elements 2 included in conductive brushes of electrodes for inspection are made of thin and narrow amorphous alloy of a certain length having a small rectangle cross section, and are fixed on a conductive holder 1 in a line at certain intervals in the width direction to form a brush shape. By allowing each contact elements to only bend in the conveyance direction and not to bent in the lateral direction, the contact elements are not made a part right and left when contacting with a circular arc-shaped cross section of the object to be inspected.
