To optimize the spraying speed and spraying range of spray coating.
The atomizer head of a spray coating device 12 includes: a liquid exit 214 which is communicating with a liquid passage 226; an air exit 212 which is arranged coaxially with the liquid exit and also communicating with air passages 252, 254; a plurality of first shaping air orifices 216, 218 which are communicating with the air passages and which have a central axis that converges at a first position at a prescribed first acute angle to a longitudinal central axis; a plurality of second shaping air orifices 220, 222 which are communicating with the air passages and which have a central axis that converges at a second position at a prescribed second acute angle to a longitudinal central axis. The first and the second acute angles are different from each other and the first and the second positions are sequentially arranged along the longitudinal central axis.
