Abstract

A thermoplastic resin-combined glass fiber base material, which comprises a glass fiber strand having a plurality of glass monofilaments bundled and a thermoplastic resin impregnated thereto, and which: PA1 A) has a string form with an average diameter of from 0.2 to 1.5 mm, PA1 B) has a glass content of from 15 to 80 vol %, PA1 C) has an impregnation rate of the thermoplastic resin of at least 95%, and PA1 D) satisfies R.ltoreq.30D.times.V, where R is the radius of curvature (mm) representing the buckling limit in bending, D is the average diameter (mm), and V is the glass content (vol %/100).
