Burner and cooking utensil

The burner comprises a first body and a second body, the second body and the first body are connected with each other through at least one first connecting structure, a containing cavity and a plurality of fire holes are formed between the second body and the first body, and the containing cavity is used for being communicated with a gas pipeline. The multiple fire holes are formed in the preset direction at intervals and communicate with the containing cavity, and the multiple fire holes are used for spraying out fuel gas. Wherein the first body is arranged at the top of the second body, at the connecting position of the first body and the second body, the first connecting structure blocks communication of the fire holes and the containing cavity, the second body is provided with a first fire transfer runner, the first fire transfer runner is arranged on the outer sides of the multiple fire holes, and the first fire transfer runner is used for fire transfer between every two adjacent fire holes. The flame in the first fire transfer runner can supplement the positions of the blocked fire holes, so that the fire holes on the two adjacent sides of the blocked fire holes are ignited to realize fire transfer, and the problem of poor fire transfer at the riveting position is avoided.
