Claim:
1. A component mounting method for making a mounting head to which a component holder is attached perform component mounting operation including upward and downward movement operation with respect to a board conveyed in a board conveyance direction and mounting each component held by the component holder on the board, the component mounting method comprising: a low-height component mounting step of mounting a low-height component on the board; and a high-height component mounting step of mounting a high-height component on the board on which the low-height component is mounted, wherein the low-height component is a component capable of avoiding interference with a low-height component already mounted on the board by upward and downward movement operation of the component holder, the high-height component is a component which can avoid interference with the low-height component already mounted on the board by upward and downward movement operation of the component holder but cannot avoid interference with a high-height component already mounted on the board by upward and downward movement operation of the component holder, and the high-height component mounting step includes repeating reciprocating mounting operations in which the component holder is moved in a mounting order relative to a reference line extending in a first direction which is the board conveyance direction such that the component holder is advanced over the board in a second direction orthogonal to the first direction and then a high-height component held by the component holder is mounted and thereafter the component holder is retracted from the board in the second direction, wherein the mounting order is set in order in which a mounting coordinate of the high-height component is larger in the second direction relative to the reference line.
