PROBLEM TO BE SOLVED: To provide a high frequency heating cooking apparatus minimizing dielectric heating to an object to be heated, and realizing heating by almost just direct heating by microwaves when carrying out direct heat heating of a surface of the object to be heated by using a dielectric heating effect from an interior of the object to be heated using microwaves, and conductive heat of an exothermic material generating heat by irradiation of microwaves. SOLUTION: An exothermic body 27b being an electric wave absorber mainly composed of ferrite is provided on a bottom face, and a metal mounting tray 27 for the object to be heated is attached by fastening to rail parts 28 provided on left and right wall surfaces 13, 14 of a heating chamber 10. By applying the microwaves in a state of directing an electric wave radiating means 22 of an antenna 21 toward a right side wall surface 11, a wraparound of electric waves to an upper side of the mounting tray 27 is suppressed, and the microwaves are efficiently absorbed by the exothermic body 27b being an electric wave absorber.
