Abstract
An electronic component handler including a first holding section and a second holding section holding an electronic component by adsorption, a suction section giving the first holding section and the second holding section an adsorption force to adsorb the electronic component, a suction flow path, a first branch flow path, a second branch flow path, a first opening/closing section opening and closing the first branch flow path, a second opening/closing section opening and closing the second branch flow path, a first pressure measurement section measuring first pressure inside the first branch flow path, a second pressure measurement section measuring second pressure inside the second branch flow path, and a control section, in which the control section opens the first branch flow path by the first opening/closing section and causes the first holding section to adsorb the electronic component, and checks whether or not the first pressure is lower than preset pressure when the second branch flow path is opened by the second opening/closing section.
