Electrical connection box and wire harness

A wire harness comprising:

• a conductive wiring material;
• and
• an electrical connection box electrically connected to the wiring material, wherein
• the electrical connection box includes:
• a substrate assembly that has a substrate on which an electronic component electrically connected to the wiring material is provided and a conductive member extended from the substrate, the substrate and the conductive member being assembled to each other;
• and
• a housing comprising a housing space portion that is internally formed to house the substrate assembly, and:
• an insertion hole that communicates internally and externally with the housing space portion to receive the conductive member along an insertion direction,
• a first flexible rib that is extended along the insertion direction, elastically deformable along first and second deforming directions that are opposite to each other and cross the insertion direction, and restricts movement of the substrate assembly towards the first deforming direction,
• a second flexible rib that is extended along the insertion direction, elastically deformable along the first and second deforming directions, and restricts movement of the substrate assembly towards the second deforming direction, and
• a boss portion that is extended along the insertion direction and restricts movement of the substrate assembly along both the first and second deforming directions.
