Disclosed is a semi-cured body having a reduced surface roughness in a surface having been subjected to a roughening process.  When a metal layer is formed on the surface of a cured body which is obtained by curing the semi-cured body, the adhesion strength between the cured body and the metal layer is increased because of the semi-cured body.  Also disclosed is a multilayer body using the semi-cured body. A semi-cured body (1) is obtained by roughening a reaction product which is produced by reacting a resin composition containing an epoxy resin, a curing agent and a silica component obtained by surface-treating silica particles having an average particle diameter of not more than 1 µm with a silane coupling agent, so that the gel fraction after 24-hour immersion in methyl ethyl ketone at 23°C is not less than 90%.  A multilayer body comprises a cured body obtained by curing the semi-cured body (1) and a metal layer which is formed by plating on the surface of the cured body.  The adhesion strength between the cured body and the metal layer is not less than 4.9/cm. L'invention concerne un corps semi-durci qui présente une rugosité de surface réduite dans une surface ayant été soumise à un procédé de rugosification. Lorsqu'une couche métallique est formée sur la surface d'un corps durci obtenu par le durcissement du corps semi-durci, la force d'adhérence entre le corps durci et la couche métallique est accrue en raison du corps semi-durci. L'invention concerne aussi un corps multicouche utilisant le corps semi-durci. Le corps semi-durci (1) est obtenu par la rugosification d'un produit de réaction, lequel est produit par la mise en réaction d'une composition de résine contenant une résine époxyde, d'un agent de traitement et d'un composant de silice obtenu par le traitement en surface de particules de silice dont le diamètre moyen des particules ne dépasse pas 1 µm, avec un agent de couplage au silane, de sorte que la fraction gel après immersion pendant 24 heures dans une méthyl éthyl cétone à 23°C est d'au moins 90%. Le corps multicouche comprend un corps traité obtenu par le traitement du corps semi-durci (1), et une couche métallique formée par placage sur la surface du corps durci. La force d'adhérence entre le corps durci et la couche métallique est d'au moins 4,9/cm.
