Abstract
A microwave irradiation device includes: a retainer configured to retain an irradiated object at a retaining position; a power feed tool configured to electrically be conductive with an oscillator; a power feed antenna configured to emit a microwave by power feed through conduction via the power feed tool, the power feed antenna having directivity and being arranged with an irradiation axis facing the retaining position; and a parasitic antenna that has directivity but is not fed with power, the parasitic antenna being arranged to face the power feed antenna across the retaining position and having an irradiation axis facing the retaining position.

The microwave irradiation device comprising:
- a retainer configured to retain an irradiated object at a retaining position;
- a power feed tool configured to be electrically conductive with an oscillator;
- a power feed antenna configured to emit a microwave by power feed through conduction via the power feed tool, the power feed antenna having directivity and being arranged with an irradiation axis facing the retaining position;
- and
- a parasitic antenna that has directivity but is not fed with power, the parasitic antenna being arranged to face the power feed antenna across the retaining position and having an irradiation axis facing the retaining position.
A microwave irradiation method comprising:
- irradiating an irradiated object with a microwave by feeding power to one antenna and not feeding power to another antenna, of directional antennas arranged to face each other across the irradiated object with an irradiation axis being directed to the irradiated object.
