A microwave oven includes a waveguide having an E-bend structure with multiple openings disposed on a lateral face of a heating chamber that allow the waveguide to communicate with the heating chamber. The waveguide has a first section for propagating a microwave from a magnetron toward the heating chamber, and a second section having a wide plane that abuts an outer wall of the heating chamber. The openings include at least one circularly-polarized-wave opening for generating a circularly polarized wave. A cross section of the first section orthogonally intersects a tube axis of the first section projects virtually along the tube axis of first section and onto a lateral face of the heating chamber, and the circularly-polarized-wave opening is configured such that its center is located outside the resultant projected region.

Microwave treatment apparatus

A high-frequency heating cooker of the invention includes a high-frequency generating device that generates a high-frequency wave to be supplied to a heating chamber, a cooling device that blows air to cool the high-frequency generating device, an air intake opening that takes the air blown from the cooling device disposed on a first side plate of the heating chamber to cool the high-frequency generating device into the heating chamber, an exhaust opening disposed on a second side plate of the heating chamber to discharge the air taken into the heating chamber from the air intake opening out of the heating chamber, an exhaust guide plate disposed between the second side plate and a side plate of a housing, and an excessive temperature rise preventing device disposed on the exhaust guide plate, the exhaust guide plate having an eaves structure above the excessive temperature rise preventing device.

High-frequency heating cooker

A display panel which is adapted to be mounted on an electronic apparatus, includes a first printed display layer, a transparent material layer that is provided on the first printed display layer, and a second printed display layer that is provided on the transparent material layer so as to correspond to the first printed display layer. The first printed display layer, the transparent material layer and the second printed display layer are integrally formed to each other. The second printed display layer is displayed from the first printed display layer side through the transparent material layer.
