PROBLEM TO BE SOLVED: To provide a voltage test plug for distinguishing clearly from a current test plug antecedent to wiring arrangement and additionally of handling easily fitting of a conduction angle and manufacturing at a moderate price. SOLUTION: Four terminal towers 5A, 5B, 5C and 5D are deployed on the surface 2a of a base 2 of the voltage test plug 1, projecting to each angle of a virtual rhombus 20, and moreover small apophyses 10A and 10B are deployed one-by-one to form the projection within triangles 28 and 29 partitioned by short diagonal line 22 of the virtual rhombus 20. If a U-sigmoidal shorting bar 42 for current test plug is inserted from one terminal tower of a pair of facing terminal tower toward another terminal tower, traveling direction of the shorting bar 42 is regulated by the apophyses 10A and 10B to induce to a direction shifted from the direction fitting an apex of the shorting bar 42 to the terminal of another terminal tower.
