Provided is a nebulizer that can be used in an atomic absorption spectrophotometer for atomizing sample liquid by introducing into a frame the sample sprayed using a combustion supporting gas. The nebulizer is provided with the following: a capillary tube (11) through which the sample liquid passes; a nebulizer main body (30) in which a combustion supporting gas ejection-port (12a) is formed at the periphery of the exit end of the capillary tube (11) and has the same axial outer circumference annular shape as the capillary tube (11) and in which a conical-shaped spray opening (12c) is formed expanding in the axial direction at the combustion supporting gas ejection-port (12a); and a spherical collision body (15) disposed in front of the spray opening (12c). The nebulizer is characterized in that actions such as the following are made possible: attaching a spray opening member (40) having the spray opening (12c) in front of the combustion supporting gas ejection-port (12a); and removing the spray opening member (40) from in front of the combustion supporting gas ejection-port (12a).
