An electric compressor includes a compression portion, an electric motor, a drive circuit that has a circuit board on which electronic components are mounted, a housing, and a resin member. At least one of the electronic components is held by the resin member with the resin member sandwiched between the at least one of the electronic component and the circuit board. The electronic compressor includes a first metal member that is in contact with the at least one of the electronic components, and thermally connected to the housing, a second metal member that is disposed in the resin member, and a bolt by which the first metal member and the second metal member are fastened with each other.

An electric compressor includes a compression part, an electric motor, an inverter device, and a housing. The inverter device includes an inverter circuit, a noise reduction unit, and a circuit board. The noise reduction unit includes a common mode choke coil and a smoothing capacitor. The common mode choke coil includes an annular core, a pair of winding wires, and an annular electrical conductor. The electrical conductor is split into a first metal plate and a second metal plate in a circumferential direction. The first metal plate is thermally coupled to the housing. The second metal plate is electrically connected to the first metal plate. An electrical resistance value of the first metal plate is larger than that of the second metal plate.

A structure for connecting a circuit board and an external connector includes a lead and a stress dampening unit. The lead electrically connects the circuit board and the external connector. The external connector is fitted to and removed from the lead. The stress dampening unit dampens stress applied to the circuit board by the lead when the external connector is fitted to and removed from the lead.

A transparent substrate used for an area light emitting device. The transparent substrate comprises a light incidence surface and a light exit surface opposite to the light incidence surface. A plurality of recesses are formed on the light exit surface bulged towards the light incidence surface. Each recess has a shape approximately corresponding to a portion of an oval sphere. Each recess perimeter on the light exit surface is approximately circle. Each recess is separately formed from other recesses.
