Abstract: A harness member includes a cable, a housing with an insertion hole through which the cable is inserted, a heat-shrink tubing covering the housing and the cable exposed on one side from the insertion hole, and a hot melt adhesive to seal between the heat-shrink tubing and the cable and between the heat-shrink tubing and the housing. A recess is formed on the housing so as to be recessed from an outer circumferential surface covered with the heat-shrink tubing. At least a portion of the hot melt adhesive melted between the outer circumferential surface of the housing and an inner circumferential surface of the heat-shrink tubing has flowed into the recess.

Abstract: A resin-sealed electronic component includes an electronic component main body sealed with a resin housing. The resin housing includes a pair of resin members aligned in a first direction with sandwiching a housing space housing the electronic component main body, and a sealing member including a molding resin and being molded so as to cover at least a portion of each of the pair of resin members. A portion of one resin member of the pair of resin members and a portion of the other resin member are aligned in a second direction intersecting the first direction to constitute a suppression structure that suppresses the molding resin from entering the housing space.

Abstract: An electric current sensor includes first, second, and third current sensor modules, each including at least one bus bar formed in a rectangular shape extending in a width direction in cross section, to carry an electric current along a length direction perpendicular to the width direction, one pair of shield plates made of a magnetic material and disposed in a height direction perpendicular to the width direction and the length direction in such a manner as to sandwich the at least one bus bar therebetween, and at least one magnetic detection element disposed between the at least one bus bar and one of the one pair of shield plates, to detect a strength of a magnetic field in the width direction. The first, the second, and the third current sensor modules are arranged by superposition on top of each other in the height direction.
