A camera module is configured to capture an optical image of a target area and includes a lens member, an imager, a light transmitting member, and a seat. The lens member is configured to receive light from the target area. The imager has a curved portion convex in a direction away from the lens member and is configured to capture the optical image formed on the curved portion. The light transmitting member optically couples the lens member and the imager. The seat has a supporting portion that supports an outer rim of the imager and a fluid space defined inside the supporting portion. A heat dissipation fluid undergoes convection in the fluid space. The curved portion is interposed between the light transmitting member and the seat having the supporting portion and the fluid space.

Electrode pads disposed on a first surface of a semiconductor element include a first pad located close to a corner and a second pad located apart from the corner compared with the first pad. A first wire connected to the first pad has a smaller Young's modulus than a second wire connected to the second pad. A thickness of an intermetallic compound layer formed by the first wire and the first pad is larger than a thickness of an intermetallic compound layer formed by the second wire and the second pad.

Semiconductor device

An electronic device includes a heat sink, a substrate mounted on the heat sink, a coating layer formed on the substrate, a lead frame fixed to the heat sink, and a mold resin sealing the substrate and the lead frame. The coating layer is made of one of a polyimide-based resin and a polyamideimide-based resin. The lead frame has a fixing terminal fixed to the heat sink through an adhesive layer. The adhesive layer is made of the same material as the coating layer.
