The present invention relates to a coil testing device which includes a device frame; an inner photographing member which is mounted on a first extension unit of the device frame and which photographs the inner side of the coil; and an outer photographing member which is mounted on a second extension unit of the device frame and which photographs the outer side of the device. The photographing members photograph the inner and outer sides of the coil at the same time so that whether a defective coil exists or not is tested. According to the present invention, damage to the coil caused by high temperatures is prevented, and the inner and outer sides of the coil are precisely tested. ylene sulfide resin(A) which an end group of polyarylene sulfide backbones is partially converted into a carboxy group; and 5-40 wt% of an olefin group elastomer(B) containing an epoxy group. |
