Contacting nose portions 5 and positioning knob portions 7 are formed side by side on contacting elements 4 of contacts 2 respectively. A positioning member 8 is disposed across the contacting elements 4 group. By inserting the positioning knob portions 7 into the positioning holes 9 formed in the positioning member 8 respectively, the adjacent contacting elements 4 and the adjacent contacting nose portions 5 can be isolated, and relative position can be obtained. <IMAGE>
