  As a result, the outer lid 4 is provided with a curved surface in the left-right direction and the front-rear direction, and has a vertically long liquid crystal E that is long in the front-rear direction in the front-rear direction of the outer lid 4 and a display portion 42 a viewed from the front side of the main body 2. It is possible to provide an easy-to-see display rice cooker.

  The surface of the outer lid 4 is formed with an arc R1 in the front-rear direction and with an arc R2 in the left-right direction. By providing the vertically long liquid crystal E in the front and rear direction of the outer lid 4, the upper wall of the liquid crystal can be lowered on the front side and the back side of the vertically long liquid crystal E. Therefore, it is easy to see the display portion 42a viewed from the front side of the main body 2. This is because the back wall does not appear conspicuously, and a liquid crystal display is reflected on the back wall, so that it is not difficult to see. Further, since the near side wall is low on the near side, the content displayed on the near end of the liquid crystal E is not hidden by the near wall and is difficult to see.
