Abstract:
A method of manufacturing a three-dimensional printed wiring board, said method comprising the steps of providing a filmy insulator comprising a thermoplastic resin composition containing 65-35 wt % of a polyaryl ketone resin having a crystal-melting peak temperature of 260Â° C. or over, and 35-65 wt % of an amorphous polyetherimide resin, and having a glass transition temperature as measured when the temperature is increased for differential scanning calorie measurement of 150-230Â° C., superposing a conductor foil on one or both sides of said filmy insulator, heat-fusing said conductor foil so that said thermoplastic resin composition will satisfy the relation between the crystal-melting calorie &Dgr; Hm and the crystallizing calorie &Dgr; Hc as expressed ((&Dgr;Hmâˆ’&Dgr;Hc)/&Dgr;Hm)&lE;0.5, etching said conductor foil to form a conductor circuit, and deforming the printed wiring circuit obtained three-dimensionally.
