The dc Josephson current in the equal spin pairing superconducting tunnel junction is calculated in this paper. It is shown that the current phase relation is I∝sin 4φ when the orbital pairing symmetries of the two superconductors fall into the irreducible representations A and 2E of the magnetic point group D4, respectively.
