PROBLEM TO BE SOLVED: To provide an induction cooking vessel in which the heat generation elements of a magnetic substance are firmly fixed to a receptacle body of non-magnetic metal. SOLUTION: The induction cooking vessel includes the receptacle body 14 and the heat generation parameter 20 of the magnetic substance which heats the bottom of the body 14. Two or more arc-shaped pressure welding elements 11, which are arranged while maintaining space in a circumference direction on each circumference of each radius which gradually becomes large with the center of the bottom as a reference point, are formed on the bottom of the body 14. Each heat generation elements 20 includes two or more first induction parts 24 radially extended and two or more second induction parts 26 which intersect with each of the first induction parts 24 and are arranged concentrically, and an insertion aperture 22, which is surrounded by space between two adjacent first induction parts and space between two adjacent second induction parts, is formed. The two or more pressure welding elements 11 prepared on the bottom of the body 14 are inserted into the respective insertion apertures 22 of the heat generation element 20 and then the pressure welding elements 11 are plastically deformed by press working and then fixed to the bottom of the body 14.
