Connector housing
A connector housing includes a housing main body and a latch arm having a latch arm main body and a latch portion protruding from the latch arm main body. The latch arm main body is formed of a first material, extends like a cantilever from the housing main body, and is elastically deformable with respect to the housing main body. The latch portion is formed of a second material having a higher rigidity than the first material and latches with a latched member. A transition region between the first material and the second material has a continuously changing mixing ratio between the first material and the second material.
1. A connector housing, comprising:
a housing main body; and
