A mist blower (10) for spraying chemical liquid includes a blast pipe (60) configured to allow air supplied from a fan (50) to flow through and to be discharged from an front end of the blast pipe (60), the chemical liquid being sprayed by mixing the chemical liquid into the air flowing through the blast pipe (60) and a diffusion cover (80) provided in the front end of the blast pipe (60) to radially outwardly diffuse the air containing the chemical liquid which is being discharged from the blast pipe (60). The diffusion cover (80) includes: a flow directing fin (81) configured to direct flow of the air containing the chemical liquid which is being discharged from the blast pipe (60) and a diffusion fin (82) configured to tilt radially outward with a greater angle than of the directing fins (81) and to radially outwardly guide part of the air containing the chemical liquid.
