Embodiment 1
[0076] Prepare bisphenol A type epoxy resin ("RE-310S" produced by Nippon Kayaku Co., Ltd., liquid at 25°C (viscosity 13000-17000mPa s), epoxy equivalent 175-190g / eq), containing latent Composition of curing agent ("Novacure HX-3722" produced by Asahi Kasei Co.), allylated novolak resin ("MEH8000H" produced by Meiwa Plastic Industry Co., Ltd., liquid at 25°C (viscosity 2000±1000mPa·s ), hydroxyl equivalent weight 141±2g / eq), silane coupling agent (γ-glycidoxypropyl trimethoxysilane) and organic acid (barbituric acid), according to the mixing ratio shown in Table 1 These materials are mixed to prepare a one-part epoxy resin composition.
[0077] "Novacure HX-3722" manufactured by Asahi Kasei Co., Ltd. is a composition containing a latent curing agent. The content of latent curing agent in "Novacure HX-3722" is 30-40% by weight.
[0078] Next, the properties of the obtained curable resin composition were measured as follows. The measurement results are shown in Table 1.

Embodiment 2
[0090] A curable resin composition was prepared in the same manner as in Example 1 except that the amount of each material used was changed to the value shown in Table 1, and its properties were measured. The measurement results are shown in Table 1.
Embodiment 3
[0092] A curable resin composition was prepared in the same manner as in Example 1, and its properties were measured, except that 0.4 parts of triethyl borate was used instead of barbituric acid and the amount of each material used was changed to the value shown in Table 1. The measurement results are shown in Table 1.
