| 摘要 | Disclosed is a prepreg including a fiber substrate and a layer made of a thermosetting resin composition, wherein the layer made of a thermosetting resin composition contains a modified silicone oil or a compound having a skeleton derived from a modified silicone oil, and the layer made of a thermosetting resin composition has a phase separation structure.;A prepreg having excellent low thermal expansion properties and warpage characteristics which are difficult to be realized by using only a conventional resin which is effective for highly filling an inorganic filler or has a low coefficient of thermal expansion, and a laminate using the same, and a printed wiring board can be provided. | ||

| 主权项 | 1. A prepreg comprising a fiber substrate and a layer made of a thermosetting resin composition, wherein the layer made of the thermosetting resin composition contains a modified silicone oil or a compound having a skeleton derived from a modified silicone oil, and the layer made of a thermosetting resin composition has a phase separation structure, said phase separation structure being a sea-island structure, wherein an occupying area ratio of an island portion of the sea-island structure per unit area on an observation surface of the layer made of a thermosetting resin composition is 10% or more to 45% or less, and wherein the thermosetting resin composition contains at least one of a cyanate resin and an unsaturated imide resin. | ||
