High-field ESR measurements were performed in Δ-chain compound [Cu(bpy)H2O][Cu(bpy)(mal)H2O](ClO4) 2, which consists spin trimers with ferromagnetic and antiferromagnetic competing exchange interactions. A narrow EPR absorption line of Cu2+ and its anomalous temperature dependence were observed. The g-shift and frequency-dependent line width of this substance in the low-temperature region are discussed.
