To enable a cooking stove burner to be successfully ignited in any one of high heat and medium heat ignition specifications without changing the burner cap, the cooking stove burner provided on the under surface of a burner cap 2 with an ignition burner port portion 5 including an ignition burner port 51 through which an air-fuel mixture in the burner body is ejected to a target 23 and a pair of fire transfer burner ports 52 positioned on circumferential both sides of the ignition burner port.

A pair of inlets 56 for introducing the air-fuel mixture in the burner body to the ignition burner port portion 5 is provided facing the diametrical inside of a pair of partition walls 54 partitioning the ignition burner port 51 from both of fire transfer burner ports 52. A distribution groove 57 is diametrically formed between the both inlets 56 and the both partition walls 54 on the under surface of the burner cap 2 from the position diametrically and inwardly adjacent to the ignition burner port 51 to the positions diametrically and inwardly adjacent to each of the fire transfer burner ports 52. The fire transfer burner ports 52 and the distribution groove 57 are upwardly and more deeply hollowed than the ignition burner port 51.
