    Abstract: A semiconductor light-emitting device includes: a board including a front surface, a back surface facing an opposite side of the front surface, a first wiring pattern formed on the front surface, and a second wiring pattern formed on the side of the back surface with respect to the first wiring pattern; and a light-emitting element, a switching element, and a capacitor, which are electrically connected to one another by both the first wiring pattern and the second wiring pattern. Among the light-emitting element, the switching element, and the capacitor, a first predetermined element and a second predetermined element are arranged in a first direction and the second predetermined element and a third predetermined element are arranged in a second direction. The second wiring pattern forms a second current path opposite to a direction of a first current path. The second current path overlaps the first current path.

    Abstract: A core body thermometer that includes a wiring substrate on which a power supply switch and electronic components are mounted. The power supply switch is housed so as to face a back surface of an upper exterior body in a space formed by the upper exterior body and a lower exterior body. Moreover, a lining member is formed in a thin plate shape and disposed on the back surface of the upper exterior body, and a buffer member is disposed between the wiring substrate and the lining member. The lining member has a through-hole in which the power supply switch is placed in an inner side in a thickness direction when viewed in a plan view, and has flexibility in an operation direction of the power supply switch).

    Abstract: A backlight module of an illuminated keyboard device includes a circuit board and a plurality of light-emitting elements. The circuit board has a top surface and a bottom surface opposite to the top surface. The top surface has a plurality of key assembling regions. Each of the key assembling regions has a stress release hole defined through the top surface and the bottom surface. The light-emitting elements are respectively disposed on the key assembling regions. Each of the light-emitting elements includes a main body and a conductive portion connected to the main body. The conductive portion is electrically connected to the circuit board, and the stress release hole is adjacent to the conductive portion of each of the light-emitting elements.
