Various cookers including the induction heating cooker as described above include an operation panel provided on the front surface of the main body. The operation panel includes electronic components such as a power switch and a display lamp arranged on an operation panel cover attached to the front surface of the main body. Such an electronic component is mounted on a board attached to the back side of the operation panel cover, and wiring for connecting to another circuit board installed inside the main body extends from the board. And the connector part for connecting the wiring extended from the operation panel side to the circuit board side of the main-body part side is provided.
The connector part includes a male connector provided at the tip of the wiring and a female connector provided on the circuit board on the main body part side.

To assemble the operation panel as described above, first, a board on which electronic components such as a power switch and a display lamp are mounted is attached to the operation panel cover. The electronic component is electrically connected to the circuit board by being inserted into the female connector provided on the circuit board on the part side. The connection of the male connector to the female connector can usually be made by snap-in engagement. Thereafter, the operation panel cover is fixed to the front surface of the main body by screws or the like while accommodating the wiring so as to be hidden behind the operation panel cover.

By the way, in the conventional operation panel, since the circuit board installed in the main body part side of the cooker is accommodated in the main body part, the female connector on the circuit board was also arranged in a state hidden in the main body part of the cooker. . Therefore, in a state where the operation panel cover is removed from the front surface of the main body portion, the structure is such that the connection location between the male connector and the female connector cannot be easily reached. Therefore, when assembling and disassembling the operation panel or replacing electronic components such as a power switch provided in the operation panel, disassemble the main body of the cooker to open the circuit board, or remove the circuit board from the main body. The operation | work for making it reach to the connection location of a male connector and a female connector by removing was required. For this reason, there has been a problem that it takes time and effort to assemble and disassemble the operation panel or to replace electronic components provided on the operation panel.
