Does Mage Armour count as an armour?

Hi there, Midgardians!

I'm pretty sure that this is a silly question, but I'm currently playing a Bladesinging Wizard (5.5), and one of the subclass' traits is the Bladesong, which grants me a AC bonus for 1 minute as long as I don't wear any armour. My question is: does Mage Armour count as an armour?

Thanks in advance.

The end of the spell says the below which implies it is not armor.

...The spell ends early if the target dons armor.

No.

Here is an SAC answer about it (check out the ones above too as they deal with the same issue).

I find it confusing that the Mage Armor spell is named that when it doesn’t count as armor.

Some spells and class features have figurative, not literal, names. The text of the spell or class feature explains what it does.

Thank you, guys! I appreciate your help.
