With this configuration, when the electric connection box 1 is fitted with the block 3A in the fitting space 46A, the arched wall 49a is elastically deformed and bent, so that the force required to fit the block 3A is required. It can suppress that it becomes relatively large. As a result, the electrical connection box 1 can suppress deterioration in workability when fitting the block 3A into the fitting space portion 46A. In addition, the electric connection box 1 and the wire harness WH1 can appropriately suppress the rattling between the block 3A and the housing 4 by the arched wall portion 49a.
