Abstract: An electrical connection box includes a housing having a temporary fixing projection. The temporary fixing projection includes a locking portion and a plate spring portion. The locking portion is provided with a locking claw projecting toward an outside in a radial direction. The plate spring portion includes a flat surface. In a temporary fixing state where the temporary fixing projection is inserted into a temporary fixing hole of an attachment panel, a locking surface of the locking claw of the locking portion faces a facing surface in an insertion direction. In the temporary fixing state, the plate spring portion is elastically deformed toward an inside in the radial direction. The flat surface of the plate spring portion is in contact with a contact surface and applies, to the attachment panel, a restoring force toward the outside in the radial direction.
