## Abstract

An electric wire with a terminal is formed by coating a crimp terminal and a crimp connection portion of an electric wire with an anti-corrosive material. When the electric wire with a terminal is manufactured, in a step of setting the terminal in a mold, in a position within a cavity corresponding to the upper surface of a front end of the anti-corrosive material, a release promoting member for promoting release of the mold from a resin is arranged, and in such a state, the anti-corrosive material is molded.

## Claims

### Claim 1

An electric wire with a terminal, comprising:
an electric wire which includes a conductor and an insulating coating to coat the conductor;
a crimp terminal which includes a conductor crimp portion that is crimp-connected to the conductor in a state where an exposed portion of the conductor protruding forward from the insulating coating at a terminal of the electric wire is placed on a terminal bottom plate extended in a forward/backward direction;
an anti-corrosive material which is made of resin and molded integrally with the electric wire and the crimp terminal so as to coat the conductor, a circumference of a crimp connection portion of the crimp terminal and a circumference of the insulating coating adjacent to the crimp connection portion; and
a release promoting member which is arranged on a front side of the crimp connection portion and a front end of the conductor and in a position of an upper surface of a front end portion of the anti-corrosive material, which is brought into close contact with an upper surface of an inner wall of a cavity in a mold for molding the anti-corrosive material when the anti-corrosive material is molded and which promotes release of the mold from the resin forming the anti-corrosive material when the mold is released.

### Claim 2 (depends on 1)

The electric wire with a terminal according to claim 1,
wherein the release promoting member is made of the same type of metal plate as the crimp terminal.

### Claim 3 (depends on 1)

The electric wire with a terminal according to claim 1,
wherein the release promoting member can be removed from the electric wire as a commercial product.

### Claim 4 (depends on 1)

The electric wire with a terminal according to claim 1,
wherein the release promoting member is placed so as to be bridged between upper ends of both left and right side plates of the connection portion in the crimp terminal.
