PROBLEM TO BE SOLVED: To narrow an interval between a pair of installation hole parts on the basis of an optical sensor where the pair of installation hole parts for installing the optical sensor on site are placed with a cable extended inside and outside in between.SOLUTION: In a distal end part (a non-covered area) of a cable 154 extended from a circuit board 182, a core wire 154a in a bare state of being exposed outside is soldered to a land 190 of the circuit board 182. Typically, a plurality of core wires 154a in the non-covered area in the bare state by removing cable sheaths are twisted at 90 degrees and formed into one column in a depth direction of a neck groove 166, and are attached to the neck grooved 166 in the column state. An insulation property mold member 210 provided with a shape complementary to a passage form of a cable arrangement passage defined by the neck grooved 166 is engaged with the neck groove. |
