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, a communicating flow channel 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 plurality of fire holes are communicated with the accommodating cavity and are used for spraying out fuel gas; wherein the first connecting structures and the edge of the combustor are arranged at intervals, at the connecting position of the first body and the second body, the first connecting structures block communication of the fire holes and the containing cavity, each first connecting structure is correspondingly provided with a communicating flow channel, and the blocked fire holes communicate with at least one adjacent fire hole through the communicating flow channels. According to the technical scheme, the communicating flow channel communicates the blocked fire hole with at least one adjacent fire hole, so that fuel gas can enter the blocked fire hole and is sprayed out through the blocked fire hole to be ignited, and the problem of poor fire transfer at the riveting position is avoided.
