Electronic component handler and electronic component tester

An electronic component tester comprising:

• a first holder that is movable in a first direction and a second direction different from the first direction and is capable of holding an electronic component;
• a second holder that is movable in the first direction and the second direction independently of the first holder and is capable of holding the electronic component;
• a light irradiation section that is arranged so as to be capable of irradiating an electronic component placement portion, on which the electronic component is placed, with light through a gap between the first holder and the second holder;
• an imaging section that is capable of imaging the electronic component placement portion irradiated with the light in the first direction;
• and
• a test unit that tests the electronic component, and
• wherein it is determined whether or not the electronic component is placed on the electronic component placement portion based on the imaging result obtained by imaging by the imaging section.
