PROBLEM TO BE SOLVED: To eliminate a static electricity absorbing part, and to protect an internal circuit from the static electricity by forming each conductor exposed part, which is to be connected to a ground pattern of a substrate, opposite to a branch terminal of a through connector arranged so as to ride over a wiring pattern. SOLUTION: In a through connector 25, each arm part 41 projected from both sides of a base body 25a, from which a through terminal 27 is hanged, so as to form each branch terminal 37. Consequently, when the tip of the terminals 37 are inserted into branch terminal lands 35, the arm parts 41 are arranged so as to ride over a right and left wiring patterns 29. This pattern 29 is not coated with the resist 33, and a loop-shaped conductor exposed part 45 is formed around a long hole 23. This exposed part 45 is formed as close as possible to the connector 25, for example, at the arm part 41. When the static electricity is charged from a charged material to the connector 25, the static electricity is discharged to the conductor exposed part 45 from the arm parts 41 of the connector 25 or the lands 35 before the static electricity flows to the internal circuit. Electric parts inside of an electronic unit, which is weak against the static electricity, is thereby protected. |
