A splice box includes: a housing including chambers each partitioned with each of partition walls, and slits each provided at each of the partition walls; and a splice terminals each including a terminal body portion inserted into and thereby received in each of the chambers, a pair of contact portions made to protrude from respective sides of the terminal body portion and arranged at the slits. A first contact portion and a second contact portion of each pair of adjacent splice terminals contact each other. Each of the chambers is provided with a pair of elastic portions so contacting side wall portions on respective sides of the terminal body portion as to have elastic deformation, and each of the elastic portions has a deformation portion formed by a part of the partition wall and a contact protrusion portion protruding from the deformation portion to the chamber side.
