A terminal-fitted electric wire improves in anticorrosion property by using the agent. The anticorrosive agent contains a base oil (A) having a viscosity of 30 mPa·s or higher at 100° C., and a metal adsorbent (B) containing a phosphorus compound. The mass composition ratio (A):(B) of the base oil (A) and the metal adsorbent (B) is within a range of 50:50 to 98:2. In the terminal-fitted electric wire, an electric connection part between a terminal and an electric conductor is covered with a film of the anticorrosive agent. ## Claims ### Claim 1 An anticorrosive agent comprising: a base oil (A) having a viscosity of 100 mPa·s or higher at 100° C., and a metal adsorbent (B) comprising a phosphorus compound, wherein a mass composition ratio (A):(B) of the base oil (A) and the metal adsorbent (B) is within a range of 50:50 to 98:2. ### Claim 2 (depends on 1) The anticorrosive agent according to claim 1, wherein the metal adsorbent (b) is a composition of a phosphorus compound comprising one or more compounds represented by the general formulae (1) and (2) and a metal: where X1 to X7 each represent independently an oxygen atom or a sulfur atom, R11 to R13 each represent independently a hydrogen atom or a hydrocarbon group having 1 to 30 carbon atoms, among which at least one is a hydrocarbon group having 1 to 30 carbon atoms, and R14 to R16 each represent independently a hydrogen atom or a hydrocarbon group having 1 to 30 carbon atom among which at least one is a hydrocarbon group having 1 to 30 carbon atoms. ### Claim 3 (depends on 1) The anticorrosive agent according to claim 1, wherein the phosphorus compound has one or more branched linear structures or one or more carbon-carbon double bond structures in the structure of the hydrocarbon groups. ### Claim 4 (depends on 1) The anticorrosive agent according to claim 1, wherein the metal forming the composition together with the phosphorus compound is at least one selected from alkali metals, alkaline earth metals, aluminum, titanium, and zinc. ### Claim 5 (depends on 1) The anticorrosive agent according to claim 1, wherein the composition of the phosphorus compound and the metal has a molecular weight of 3000 or lower. ### Claim 6 (depends on 1) A terminal-fitted electric wire, wherein an electric connection part between a terminal and an electric conductor is covered with the anticorrosive agent according to claim 1. ### Claim 7 (depends on 2) The anticorrosive agent according to claim 2, wherein the phosphorus compound has one or more branched linear structures or one or more carbon-carbon double bond structures in the structure of the hydrocarbon groups. ### Claim 8 (depends on 7) The anticorrosive agent according to claim 7, wherein the metal forming the composition together with the phosphorus compound is at least one selected from alkali metals, alkaline earth metals, aluminum, titanium, and zinc. ### Claim 9 (depends on 8) The anticorrosive agent according to claim 8, wherein the composition of the phosphorus compound and the metal has a molecular weight of 3000 or lower. ### Claim 10 (depends on 9) A terminal-fitted electric wire, wherein an electric connection part between a terminal and an electric conductor is covered with the anticorrosive agent according to claim 9.
