PROBLEM TO BE SOLVED: To provide input/output terminals which are capable of preventing high-frequency signals from deviating in phase so as to improve them in transmission characteristics, and to provide a semiconductor element housing package and a semiconductor device. SOLUTION: The input/output terminal 3 comprises a flat plate part 3a where a first differential line A composed of two parallel line conductors 3b on its top surface and first grounding conductors 3c are formed, an upright wall part 3d which is bonded on the top surface of the flat plate unit 3a so as to cover the other side ends of the first differential line A and the first grounding conductors 3c; a second differential line B composed of two parallel line conductors 3b' formed on the upper main surface of the upright wall 3d and second grounding conductors 3c'; a signal through conductor 9 which is provided on the upright wall 3d so as to electrically connect the first and second differential line conductor A and B, together; and a grounding through conductor 10 which is provided on the upright wall 3d so as to electrically connect the first and second grounding conductor, 3c and 3c', together.
