Zusammenfassung:	To provide a polyamide composition which exhibits good welding strength and appearance when laser welded, and has excellent rigidity under an atmospheric equilibrium water absorption when formed into a molded article and good moldability.SOLUTION: There is provided a polyamide composition which comprises (A) a crystalline polyamide, (B) an amorphous polyamide, and (C) a laser light transmitting colorant, wherein the melting point (Tm) of the crystalline polyamide (A) is 290.0°C or less as measured by differential scanning calorimetry, the content of the amorphous polyamide (B) is 10.0 mass% or more and 50.0 mass% or less based on the mass of the total polyamide in the polyamide composition, and the amorphous polyamide (B) is dispersed in the crystalline polyamide (A) to form a domain.SELECTED DRAWING: None 【課題】レーザー溶着する際に良好な溶着強度や外観を発現し、成形品としたときの大気平衡吸湿下での剛性に優れ、且つ、成形性が良好なポリアミド組成物を提供する。【解決手段】ポリアミド組成物は、（Ａ）結晶性ポリアミド、（Ｂ）非晶性ポリアミド、及び（Ｃ）レーザー光透過性着色剤を含有する、ポリアミド組成物であって、前記（Ａ）結晶性ポリアミドの、示差走査熱量計により測定される融点（Ｔｍ）が２９０．０℃以下であり、前記（Ｂ）非晶性ポリアミドの含有量は、前記ポリアミド組成物中の全ポリアミドの質量に対して、１０．０質量％以上５０．０質量％以下であり、前記（Ｂ）非晶性ポリアミドが、前記（Ａ）結晶性ポリアミド中に分散し、ドメインを形成している。【選択図】なし
