Polyamide resin composition and polyamide molded body

A polyamide resin composition, comprising:

• a polyamide resin at a content of 20 mass % or more and 85 mass % or less based on a total mass of the polyamide resin composition;
• and
• a glass fiber at a content of 15 mass % or more and 70 mass % or less based on the total mass of the polyamide resin composition, the glass fiber containing a surface treatment agent or a sizing agent,
• wherein
• the surface treatment agent or the sizing agent has an acidic group,
• the polyamide resin contains
• a dicarboxylic acid-derived component unit (a) and a diamine-derived component unit (b),
• the dicarboxylic acid-derived component unit (a) contains
• a component unit derived from an aromatic dicarboxylic acid or an alicyclic dicarboxylic acid, and
• the diamine-derived component unit (b) contains
• a component unit (b1) derived from an alkylene diamine having 4 to 18 carbon atoms at a content of more than 50 mol % and 90 mol % or less based on a total number of moles of the diamine-derived component unit (b), and
• a component unit (b2) derived from a diamine represented by Formula (1) below at a content of 10 mol % or more and less than 50 mol % based on the total number of moles of the diamine-derived component unit (b):
• wherein, m and n are each independently 0 or 1, and —X— is a single bond or a divalent group selected from the group consisting of —O—, —S—, —SO2—, —CO— and —CH2—.
