Abstract:
A molded article including:a main body comprising a first synthetic resin;a section piece comprising a second synthetic resin, integrally molded with said main body, anda surface layer comprising a third synthetic resin molded to and overlying an upper surface of said section piece, and at least a portion of an upper surface of said main body,wherein said main body comprises a first synthetic resin having an elastic modulus in flexure in a range of about 2,000 MPa to about 4,000 MPa and a coefficient of linear thermal expansion of about 3-12.times.10.sup.-5 .degree. C..sup.-1 ;wherein said section piece comprises a second synthetic resin different from said first synthetic resin, having an elastic modulus in flexure in a range of about 100 MPa to 700 MPa and a coefficient of linear thermal expansion of about 1-10.times.10.sup.-5 .degree. C..sup.-1 ; andwherein said surface layer comprises a third synthetic resin having an elastic modulus in flexure in a range of about 300 MPa to about 2,000 MPa and a coefficient of linear thermal expansion of about 3-12.times.10.sup.-5 .degree. C..sup.-1.
