A resin sheet according to the present disclosure includes an uncured product or semi-cured product of a thermosetting resin composition. A melt viscosity of the resin sheet is equal to or greater than 10 Pa·s and equal to or less than 2000 Pa·s when measured using a Koka flow tester under a measuring condition including 130° C. and 1 MPa and is equal to or greater than 6 Pa·s and equal to or less than 1200 Pa·s when measured using the Koka flow tester under a measuring condition including 130° C. and 4 MPa.

A multilayer printed wiring board has excellent high-frequency characteristics. The multilayer printed wiring board includes one or more conductive layers and one or more insulating layers. In the multilayer printed wiring board, the one or more conductive layers and the one or more insulating layers are alternately stacked. Each insulating layer of the one or more insulating layers includes one or more of a polyolefin resin layer, a fluororesin layer, a polyphenylene ether resin layer, a polyamideimide resin layer, and a polyimide resin layer. At least one insulating layer of the one or more insulating layers includes a polyolefin resin layer.

An information processing apparatus which comprising a recording section for recording information in a removable recording medium, a switch, a computer, a power supply section for supplying power to the recording section and the computer, and an operating system which is software for controlling the computer. The power supply section controls power supply to the recording section and the computer individually and, only the power supply to the recording section is controlled ON/OFF corresponding to a state of the switch. The operating system conducts a processing based on a presumption that the recording section is not connected. Under the above-described configuration, when there is no access made to the recording section, the power supply is disconnected not only to the recording section but also to a constituent part used for making access to the recording section. Thus the advantage of low-power operation is further enhanced.
