When the blending ratio of the radical polymerization initiator is not more than the above upper limit value, the dielectric property of the crosslinked body (L) is improved, and when it is more than the above lower limit value, the heat resistance and mechanical properties of the crosslinked body (L) are improved. Can be made to.

As the radical polymerization initiator, known thermal radical polymerization initiators, photoradical polymerization initiators, and these can be used in combination.

(2) Dielectric characteristics The dielectric loss tangent of the laminate at 12 GHz was measured by the cylindrical cavity resonator method. Specifically, a network analyzer (8510B manufactured by YHP) was used to measure the dielectric loss tangent of the laminate at 12 GHz.
◯: Dissipation factor is less than 0.0025 ×: Dissipation factor is 0.0025 or more

(3) Thermal stability The obtained laminate was allowed to stand in an oven at a temperature of 200 ° C. and taken out after 100 hours. The thermal stability was evaluated from the state of the taken-out laminate.
The thermal stability of the laminate was evaluated according to the following criteria.
○: No abnormality in the laminate ×: Cracks in the laminate

[Example 9 and Comparative Example 3]
Prepregs 2 and 3 were prepared in the same manner as in Example 8 except that the resin composition varnish was changed to the resin composition varnish described in Example 6 and Comparative Example 2, respectively, and further in the same manner as in Example 8. Laminates 2 and 3 were prepared and evaluated.
The results obtained are shown in Table 2.
