The relationship between submillimeter (submm) dust emission polarization andnear-infrared (NIR) $H$-band polarization produced by dust dichroic extinctionwas studied for the cold starless dense core FeSt 1-457. The distribution ofpolarization angles ($90^{\circ}$-rotated for submm) and degrees were found tobe very different between at submm and NIR wavelengths. The mean polarizationangles for FeSt 1-457 at submm and NIR wavelengths are $132.1^{\circ} \pm22.0^{\circ}$ and $2.7^{\circ} \pm 16.2^{\circ}$, respectively. The correlationbetween $P_H$ and $A_V$ was found to be linear from outermost regions torelatively dense line of sight of $A_V \approx 25$ mag, indicating that NIRpolarization reflects overall polarization (magnetic field) structure of thecore at least in this density range. The flat $P_H/A_V$ versus $A_V$correlations were confirmed, and the polarization efficiency was found to becomparable to the observational upper limit (Jones 1989). On the other hand, asreported by Alves et al., submm polarization degrees show clear linearlydecreasing trend against $A_V$ from $A_V \approx 20$ mag to the densest center($A_V \approx 41$ mag), appearing as "polarization hole" structure. The powerlaw index for the $P_{\rm submm}$ versus $A_V$ relationship was obtained to be$\approx -1$, indicating that the alignment for the submm sensitive dust islost. These very different polarization distributions at submm and NIRwavelengths suggest that (1) there is different radiation environment at thesewavelengths or (2) submm-sensitive dust is localized or the combination ofthem.
