A paste coater that can apply an amount of a solder paste to small-diameter bump electrodes at a narrow pitch is described. A paste coater includes: a transfer roller, supported by a sub frame; a roller drive mechanism for rotating the transfer roller; a paste storage unit for storing paste to be supplied to the surface of the transfer roller; a squeegee having a distal edge, parallel to the rotary shaft of the transfer roller, separated by a gap from the distal edge to the surface of the transfer roller; a squeegee holder for holding and including biasing means for pushing the squeegee in a first direction thereby widening the gap; and a gap adjustment mechanism with biasing means for pushing the squeegee in a second direction thereby narrowing the gap.
