PROBLEM TO BE SOLVED: To provide a burner device suppressing interference between flames in a valley part lower end region in a combustion part having a three-dimensional shape, and securing a stable combustion performance. SOLUTION: The burner device is constituted in a totally primary combustion method of supplying premixed gas to the combustion part 1 having a fiber mat 10 on a retainer plate 11 with holes 110 and at least one valley part 13 formed thereon to form flames 3 on the combustion part 1. In each lower end region of both side slant faces 15, 16 of the valley part 13, a plurality of fixation parts 31 for fixing the fiber mat 10 to the retainer plate 11 and closing the fixed portion are intermittently provided along a valley fold line 13a of the valley part 13. The plurality of fixation parts 31 are arranged so that part or all of the fixation parts 31 faces a non-fixation part having no fixation part 31 in the lower end regions of the opposing slant faces 15 (16) via the valley fold line 13a.
