PROBLEM TO BE SOLVED: To obtain a contact for a vacuum interrupter capable of obtaining high magnetic field intensity and high mechanical strength. SOLUTION: In a cup-shaped contact for the vacuum interrupter, a silt 5 is formed from one end surface side of a cylindrical contact table 1, a slit 6 is formed from the other end surface side, and the optimum length in the shaft direction of the contact table 1 of the slits 5, 6 is decided based on the specified parameter when the axial length of the contact table 1 is represented by 1 and the axial length of the contact table 1 of the slits 5, 6 are represented by x, y.
